IMDb vs. Rotten Tomatoes vs. Metacritic: How Movie Ratings Really Work
By ReelsMasala Editorial · · 6 min read
Before pressing play, most of us glance at a score: a percentage on Rotten Tomatoes, a number out of ten on IMDb, maybe a colored box from Metacritic. These numbers look similar, but they measure very different things. Understanding how movie ratings work stops you from skipping a great film because of a misleading number, or being disappointed by a "98%" movie that was only pleasant.
This guide explains the four rating systems US viewers see most often, including TMDB, the community database that powers the scores on ReelsMasala, and gives a simple method for reading them together.
IMDb: the crowd's average
IMDb lets any registered user rate a title from 1 to 10. The score you see is a weighted average of those votes. IMDb says it uses filters to reduce the impact of vote-stuffing, but it does not publish the exact formula. Its famous Top 250 list uses an additional weighting that favors titles with many votes.
What it's good for: IMDb reflects how a large, general audience feels about a film after watching it. With millions of votes on popular titles, the average is fairly stable.
Watch out for: small vote counts, which can swing wildly, and organized campaigns, which can push scores up or down for reasons that have nothing to do with the film. Always check how many people voted.
Rotten Tomatoes: the Tomatometer and the Popcornmeter
Rotten Tomatoes is the most misunderstood score in entertainment. The Tomatometer is not an average rating. It is the percentage of approved critics whose review was positive. If 90 of 100 critics gave a movie a mild thumbs-up, it scores 90%, even if nobody thought it was a masterpiece.
The site also shows an audience score, now branded the Popcornmeter, based on the share of users who rated the film positively. A "Certified Fresh" badge goes to films that meet thresholds for Tomatometer score and number of reviews.
What it's good for: answering "Did most critics like this?" A high Tomatometer means a film is broadly well made and unlikely to be a disaster.
Watch out for: treating 95% as better than 85%. A crowd-pleasing film that nobody dislikes can outscore a daring film that divides critics.
Metacritic: the weighted critic average
Metacritic converts each critic's review into a score from 0 to 100 and computes a weighted average, giving more weight to some publications. Scores are color-coded: green for generally favorable, yellow for mixed and red for generally unfavorable. User scores appear separately on a 0–10 scale.
What it's good for: measuring how much critics liked a film, not just whether they liked it. A Metascore above 80 usually signals real acclaim.
Watch out for: a smaller pool of reviews than Rotten Tomatoes, and a weighting system Metacritic does not fully disclose.
TMDB: the community score behind our pages
The ratings you see on ReelsMasala posters and title pages come from The Movie Database (TMDB). Like IMDb, TMDB lets registered users rate titles from 1 to 10 and displays the average, along with a vote count in its data. TMDB has fewer voters than IMDb, so scores for obscure titles can be volatile, but for popular films they track audience sentiment closely.
For example, at the time of writing TMDB users rate The Dark Knight 8.5/10 from more than 36,000 votes, and Bong Joon Ho's Parasite 8.5/10 from more than 21,000 votes. Both are numbers you can trust because the sample is so large.
Why the scores disagree
Here are the most common reasons the same movie scores differently across sites:
- Critics vs. audiences: critics watch hundreds of films a year and value originality. General audiences often value entertainment and emotional payoff. Big franchise movies frequently score higher with audiences, and challenging art films higher with critics.
- Binary vs. average: the Tomatometer counts positive reviews, while Metacritic and IMDb average the scores. One measures consensus, the other intensity.
- Timing: scores shift over time. Some films are reappraised years later, and early audience scores can be skewed by the most enthusiastic fans.
- Sample size: a score based on 40 votes means far less than one based on 40,000.
- Review bombing: coordinated negative or positive voting can distort user scores, especially soon after release.
A simple method for reading ratings together
- Check consensus with the Tomatometer. Above about 75% suggests most critics found it worthwhile.
- Check intensity with Metacritic. Above about 75 suggests strong acclaim, and 60–74 suggests good but not great.
- Check audience enjoyment with IMDb or TMDB. About 7.0 or higher with thousands of votes usually means viewers had a good time.
- Read two reviews, one positive and one negative. The reasons matter more than the number. A "slow" film might be exactly what you want on a quiet night.
- Factor in genre. Horror and broad comedy often score lower with critics yet deliver exactly what fans want. Our beginner's guide to film genres explains why genre expectations matter.
Ratings for international films and series
Scores for non-English titles deserve extra context. On IMDb and TMDB, international films are often rated by a smaller, more self-selected audience: people who sought the film out and are likely to enjoy it. That can push scores up. On the other hand, critic aggregators may have fewer reviews of a Telugu blockbuster or a Korean drama than of a Hollywood release, so the Tomatometer may rest on a small sample.
The practical advice is the same: check the number of votes or reviews before trusting the score. For Indian, Korean and Japanese titles, it also helps to read coverage from critics who know those industries well. Our explainers on South Indian cinema and Korean movies for beginners suggest proven starting points that have held up with both audiences and critics.
What ratings can't tell you
Scores do not measure whether a film is right for your household. A movie can earn 9/10 and still be too intense for kids. For that, check the official content rating. Our explainer on MPA ratings and TV parental guidelines covers what G, PG, PG-13, R and TV-MA actually mean. Ratings also do not tell you where a film is available, so use our guide to finding where to watch any movie legally.

Frequently asked questions
Is a 90% on Rotten Tomatoes the same as a 9 out of 10?
No. A 90% Tomatometer means 90% of counted critics gave the film a positive review. It says nothing about how enthusiastic those reviews were. A film where every critic thought it was merely "good" can still score 100%.
Which movie rating site is most accurate?
None is "most accurate," because each measures something different. Rotten Tomatoes measures critical consensus, Metacritic measures the strength of critical praise, and IMDb and TMDB measure audience opinion. Using two or three together gives the clearest picture.
Where do the ratings on ReelsMasala come from?
The scores on our posters and title pages come from TMDB user ratings on a 1–10 scale. We display them as provided by the TMDB API and do not alter them.
What is a good IMDb rating?
For a title with thousands of votes, about 7.0 and above is generally considered good, about 8.0 and above excellent. Ratings below 6.0 often indicate mixed reactions, though genre and audience matter.
Why do critics and audiences disagree so often?
Critics see many films and tend to reward originality and craft. Audiences often reward entertainment, emotional payoff and loyalty to a franchise. Neither view is wrong. They simply value different things.
