Rotten Tomatoes Movie Reviews
Rotten Tomatoes is a great site for getting movie reviews on both current and video movies. They consolodate all the top movie reviewers and list their reviews creating a realistic view of what people really think. You can also find local movie listings.
In a nutshell, Rotten Tomatoes offers a fun and informative way to discover the critical reaction on movies from the nation's top print and online film critics, neatly summarized via the Tomatometer™. Which is sort of funny - the concept of throwing virtual tomatoes at a rotten movie kind of rocks. I like how they list all of the reviews and then put up the results as whole. You can also read all of the reviews. It's just a more straightforward way to choose movies you want to see.
There is even a price comparison feature for DVDs, soundtracks, video products, and stuff like that. Two thumbs up. :)
