What is the Rotten Tomatoes Tomatometer?
The Tomatometer measures the percentage of Approved Tomatometer Critics who recommend a certain movie --
or the number of good reviews divided by the total number of reviews.
A good review is denoted by a FRESH tomato.
A bad review is denoted by a ROTTEN tomato.
In order for a movie to receive an overall rating of FRESH on Rotten Tomatoes, the reading on the Tomatometer for that movie must be at
least 60%. Otherwise, it is ROTTEN. The ratings and reviews are licensed by the Phoenix Public Library from Rotten Tomatoes. For more information,
