Rotten Tomatoes is really good website to evaluate a movie before watching it.They are really genuine reviews by the users.They are much better than the biased reviews on TVs and magazines.Whenever I want to watch some movie, i always search on the Internet movie Db and rotten tomatoes for the ratings.From my experience, i should say Internet Movie Database(ImDb) have more accurate **ratings** than rotten tomatoes.
The overall rating on rotten tomatoes is really high for every movie.Looking in rotten tomatoes alone my give you a wrong idea about the movie.Rating is one thing and reviews are another.Rotten tomatoes are **better in reviews** than Imdb.Their critics reviews are outstanding.But the problem is that many of these reviews will reveal the plot by a big margin.In my personal recommendation do for Imdb for ratings of a movie and go for rotten tomatoes for reviews about the same.
