Rotten Tomatoes is a popular site that's been around since 1998, and it was been acquired by Flixster early this year. It takes the reviews of professional movie critics around the world, counts the positive (fresh) and the negative (rotten) reviews and turns them into a percentage-based grade.
Now, you can see the Tomatometer in movie descriptions on iTunes, along with a couple of blurbs taken from some of the top critics' reviews. It's a great way to quickly check out whether a movie is worth watching; if you want more info, you can jump to Rotten Tomatoes for more reviews with a click.
