This site gives you a lot of insight into the quality of movies since it compiles the reviews of several critics into an overall score. Overall, they are pretty much on the mark in their evaluation of movies.You can also follow the reviews of particular movie critics if you wish. Also, you can watch trailers, get plot summaries, cast and crew info and more. Great site!
I have been checking out this site for a number of years now to see if the latest movie releases are any good or not. For every movie that comes out they compile a whole host of reviews from movie critics from around the web and provide the reader with an average score and a general consensus review. The layout is great in that it allows you to see the overall score a movie has gotten at the top of the page and then scroll down to see a breakdown of reviews from the various critics.
This site is a great resource for any movie goer and is a must visit for anybody about to go out to the cinema. I have very rarely been disappointed by the reviews on the site and they seem to be pretty accurate predictor of how I will feel about a movie.
