Movie ratings often stir debate, especially when presented as definitive or all-encompassing. Ultimately, your own opinion is the most important. However, sites like Rotten Tomatoes, Metacritic, and IMDb can provide a general critical or audience consensus.
The "best" site to use depends on what specific information you are seeking about a movie. Often, using a combination of these sites provides the most well-rounded perspective.

Reviewer/Rater Pool | Professional Critics | Elite Professional Critics | General Public (Millions of users) |
Transparency of Method | Simple and clear (percentage) | Complex (weighted average, undisclosed weights) | Complex (hidden weighted average formula) |
Nuance | Less nuanced (binary "liked/disliked") | More nuanced (degree of quality) | Less nuanced (single average) |
Score Range | Tends to hit extreme ends (98%, 2% common) | Less extreme (98, 2 rare) | Tends to cluster in mid-range (6-8 common) |
Bias | Can favor "safe" crowd-pleasers | Less susceptible to "safe" film bias | Susceptible to fan/review bombing, popularity bias |
Use Case | Quick decision-making ("Should I see it?") | Deeper critical assessment, ranking films | General audience sentiment, movie information |
Historical Coverage | Extensive, including old movies | Mostly for movies released after 2000 | Extensive, virtually all films |
Additional Info | Critic consensus, average rating | Critic consensus, color-coded scores | Cast/crew, plot, trivia, box office, user reviews |
All three platforms offer valuable insights into critical and audience reception, but they serve different purposes.
- Rotten Tomatoes is best for a quick gauge of whether professional critics broadly endorsed a film.
- Metacritic provides a more refined understanding of professional critical consensus and the perceived quality of a film.
- IMDb is ideal for understanding general audience sentiment and for comprehensive movie and TV show data.
Here's a detailed analysis of Rotten Tomatoes, Metacritic, and IMDb, including their methodologies, pros, and cons:
Rotten Tomatoes
Rotten Tomatoes' primary metric is the Tomatometer, which reflects the percentage of approved critics who gave a movie a positive review.
Methodology:
- Reviewer Pool: Rotten Tomatoes aggregates reviews from print publications, broadcast outlets, and online publications that meet specific criteria for traffic, quality, and consistency. For popular films, over 200 different reviewers are counted.
- Positive Review Definition: Rotten Tomatoes measures the percentage of positive reviews. This means if a critic's overall sentiment is favorable, it counts as "Fresh," regardless of the specific numerical rating they might have given (e.g., a 6/10 and a 10/10 both count as positive).
- Categorization: Movies are categorized as either "Fresh" or "Rotten" based on the Tomatometer:
- Rotten: The Tomatometer is 59% or lower.
- Fresh: The Tomatometer is 60% or higher.
- Certified Fresh: Movies and TV shows achieve this distinction with a steady Tomatometer of 75% or higher after a set amount of reviews, indicating sustained critical acclaim.
- Editorial Involvement: Beyond determining whether a review is positive or negative, there is minimal editorial involvement in calculating scores.
- Average Rating: While the Tomatometer focuses on the percentage of positive reviews, Rotten Tomatoes also lists the average rating given by critics on each movie page, though it's less emphasized.
- Historical Coverage: Rotten Tomatoes has a vast archive, including reviews for older films.
Pros:
- Simplicity and Clarity: The Tomatometer is easy to understand: it's the percentage of critics who liked the movie. This immediately makes sense to a broad audience.
- Objective (in its metric): It's generally straightforward to determine if a review is positive or negative, which is the sole basis for the Tomatometer calculation.
- Consumer-Oriented: It caters to the average consumer's desire to know if a movie is "worth seeing" or "worth skipping."
- Clear Narrative: The simple "Fresh" or "Rotten" categorization provides a compelling and easily digestible narrative, which can drive page views.
- Broad Range of Scores: Rotten Tomatoes scores tend to span the entire scale, with 98% or 2% ratings being reasonably common.
- Indicates "General Positiveness": The score reflects the overall positive sentiment of reviewers and is less affected by a single "subjective" reviewer.
- Useful for Certain Viewers: It's helpful for those who:
- See movies on a whim.
- Prefer to know how popular a film is rather than how good it is.
- Believe that historically great and awful movies are released frequently.
- Equal Review Weighting (by default): Rotten Tomatoes weighs all approved reviews equally, although users can filter for "Top Critics."
- Honest Assessment: Reviewers may be more honest when simply deciding if a film is "good or bad."
- Predictive of Liking: It can provide an indication of your chances of liking a movie based on broad critical reception.
Cons:
- Oversimplification: The "Fresh" or "Rotten" categorization sacrifices nuance, potentially misleading viewers about the degree of critical approval.
- Buried Advanced Metrics: While "Top Critics" scores exist, they are often less prominent than the main Tomatometer, meaning most users won't delve deeper.
- Bloated Reviewer Pool: The inclusive approach can sometimes lead to less rigorous or "lousy" reviewers being included.
- Bias Towards "Safe" Films: Inoffensive, family-friendly films can often achieve high scores simply because they are broadly liked and take fewer risks. Ambitious or daring films that take risks might receive lower scores, even if they are ultimately more impactful.
- Limited for "Best/Worst Ever" Lists: Due to its "positive/negative" nature, Rotten Tomatoes is less useful for ranking films in terms of absolute quality. A 90%+ score could simply mean that 100% of critics thought a movie was "better than bad."
- Does Not Reflect "How Good": A 100% on Rotten Tomatoes simply means 100% of critics found the movie "worth watching" or "better than bad," not necessarily that it was an "amazing, transcendent movie."
- Misleading High Scores: A film can receive mostly slightly-above-average scores and still end up with a very high "Fresh" rating, even if no critic truly loved it.
- Crowd-Pleaser Bias: A high score might indicate a crowd-pleaser that is ultimately uninteresting because it avoids risks.
- Distributor Tool vs. Cinema Enthusiast Tool: Some argue it's more useful for distributors to gauge broad appeal than for serious cinephiles seeking deeper critical insight.
- Lukewarm Reception Can Yield High Scores: Some passionately loved films can receive relatively low numbers, while safe films with a lukewarm reception can achieve good scores.
Metacritic
Metacritic's primary metric is the Metascore, a weighted average of scores from top critics, normalized on a scale from 0 to 100.
Methodology:
- Weighted Average: The Metascore is not a simple percentage but a weighted average. This means some critics' reviews carry more weight than others based on the publication's "quality and overall stature," though Metacritic does not disclose these specific weights.
- Curated Critic Pool: Metacritic features a more exclusive group of 30-50 writers from recognized and prestigious publications, aiming for a higher standard of critical input.
- Score Normalization and Conversion: Metacritic editors convert critics' scores to fit their 0-100 model. This can be subjective, as they might assign a numerical score (e.g., 80) to a positive review that doesn't explicitly state a number but expresses reservations.
- Color-Coded Scores: Metacritic uses a color-coding system for instant comparison:
- Green Scores: "Good" Metascores and favorable reviews.
- Yellow Scores: "Average" Metascores and mixed reviews.
- Red Scores: "Bad" Metascores and unfavorable reviews.
- Historical Coverage: Metascores are predominantly available for movies released after 2000.
Pros:
- Nuance: The Metascore aims to convey how good each movie is, providing a more granular understanding of critical reception beyond a simple "liked/disliked." A 97% on Rotten Tomatoes might mean everyone liked it, but a high Metascore suggests genuine critical acclaim and even love.
- Reliable Sources: Metacritic's focus on a curated group of "best of the best" critics generally ensures a higher standard of reviews.
- More True to Life: Its weighted scoring methodology is seen by some as a more accurate reflection of the varying impact of different critical opinions.
- Less Extreme Scores: Highly extreme scores (like 98% or 2%) are less common on Metacritic compared to Rotten Tomatoes, indicating a more realistic distribution of critical opinion.
- Useful for Certain Viewers: It's helpful for those who:
- Demand to know precisely how good a film is.
- Respect established "Old Media" critics.
- Enjoy making lists of their favorite movies.
- Acknowledge that most movies are between "kinda bad" and "somewhat good," with fewer extremes.
- Captures Essence of Opinion: The single Metascore aims to encapsulate the core of critical opinion.
- Better Idea of Appreciation: As an average of critic ratings, it provides a more refined idea of the critical appreciation of the movie.
- Highlights High Acclaim: Metacritic effectively distinguishes films that receive exceptional acclaim from those that are merely positively received.
- Indicates "How Good": Metacritic aims to tell you the quality of a movie. A 100 on Metacritic signifies that critics found the movie to be amazing and transcendent.
Cons:
- Complexity: The weighted average and normalization process can be more difficult to explain and understand compared to the straightforward percentage of Rotten Tomatoes.
- Less Recognizable Branding: Metacritic has less brand recognition among the general public compared to Rotten Tomatoes.
- Subjectivity in Score Assignment: The process of converting qualitative reviews into numerical scores, especially when critics don't provide a number, can be subjective and prone to human error by Metacritic editors.
- Weighted Average Obscurity: The undisclosed weighting system can lead to a lack of transparency for some users.
- Impact of Individual Reviews: Because it's an average, one or two very negative (or positive) reviews from highly weighted critics can have a disproportionately large impact on the overall Metascore.
IMDb (Internet Movie Database)
IMDb is primarily a comprehensive database for movies, TV shows, and video games, also featuring user-generated ratings.
Methodology:
- User-Generated Ratings: IMDb's main rating system is based on user votes on a scale of 1 to 10.
- Weighted Average (hidden formula): While it appears to be a simple average, IMDb employs a proprietary weighted average formula to counteract ballot stuffing and ensure the integrity of its Top 250 lists. This formula factors in the number of votes, the average rating, and a normalization constant.
- No "Critic" Pool: IMDb does not use a panel of professional critics for its primary rating. Anyone with an IMDb account can submit a rating.
- Extensive Data: Beyond ratings, IMDb offers a vast amount of information, including cast and crew details, plot summaries, trivia, release dates, box office data, user reviews, and trailers.
Pros:
- Massive User Base: With millions of users, IMDb's ratings reflect a broad audience consensus, not just professional critics.
- Simplicity: The 1-10 rating scale is intuitive and easy for anyone to understand and use.
- Community Engagement: Users can leave detailed written reviews, discuss films on forums, and contribute trivia.
- Comprehensive Information: IMDb is an unparalleled resource for movie and TV show data, often serving as a first stop for research.
- Historical Depth: Contains information and ratings for virtually every film ever made.
- Reflects Popularity/Audience Liking: High IMDb scores generally indicate a movie is widely enjoyed by the general public.
- User-Friendly: The platform is generally easy to navigate for finding information and submitting ratings.
Cons:
- Susceptible to Bias/Manipulation: While IMDb has measures in place, user ratings can still be influenced by fan campaigns, "review bombing," or other coordinated efforts, potentially skewing scores for highly anticipated or controversial films.
- Lacks Nuance: A single numerical average (e.g., 7.5/10) doesn't explain why users liked or disliked a film or the degree of their appreciation.
- Reflects Popularity More Than Quality: A high IMDb score might indicate a movie is popular and widely appreciated by the masses, but not necessarily a critically acclaimed or artistically significant work. Some niche or complex films might receive lower scores from a general audience.
- Homogeneous Scores: Many films tend to cluster in the 6-8 range, making it harder to distinguish truly exceptional or poor films based on score alone.
- "Recency Bias": Newer, highly anticipated films can sometimes receive inflated initial scores from enthusiastic fans.
- No Professional Critical Insight: For those seeking expert critical opinions, IMDb's user-generated ratings are not a substitute.
