Understanding the Tomatometer Score
The Tomatometer score, a hallmark of Rotten Tomatoes, is a percentage representing the proportion of professional critic reviews for a given movie or TV show that are positive. It aims to provide a quick snapshot of critical reception.
How the Tomatometer Score is Calculated:
- Fresh Reviews: These are reviews from approved critics that are deemed positive.
- Rotten Reviews: These are reviews from approved critics that are deemed negative.
- Total Reviews: The sum of all Fresh and Rotten reviews.
The formula is straightforward:
(Number of Fresh Reviews / Total Number of Reviews) * 100
For example, if a movie has 150 Fresh reviews and 50 Rotten reviews:
- Total Reviews = 150 + 50 = 200
- Tomatometer Score = (150 / 200) * 100 = 75%
A score of 75% or higher is considered "Fresh," while a score below 75% is considered "Rotten." A special "Certified Fresh" distinction is awarded to movies that meet a certain threshold of both score and number of reviews.
The Audience Score:
It's important to distinguish the Tomatometer score from the Audience Score. The Audience Score is calculated based on ratings submitted by registered Rotten Tomatoes users. While both offer insights into a film's reception, they represent different perspectives: critical consensus versus viewer opinion.
