The Decomposition of Rotten Tomatoes
Rotten tomatoes is actually very useful if you know the magic formula:* If tomatometer & audience score are within 5% of each other, you can trust the ratings to give you a decent indiciation of movie quality.* If tomatometer is more than 15%+ higher than audience score, it means it's an artsy fartsy movie that critics like and movies don't.* If audience score is 15%+ higher than tomatometer, it's a fun movie even if it's not oscar worthy.
