Rotten Tomatoes is a great Web site resource for movies! There’s a lot to the site, but generally when I hear about a movie, I’ll type in the name and see what kind of reviews it’s getting. Each movie has a general “Rotten Tomatoes” rating, but you can also see the reviews of particular critics. The site is really really helpful, especially when you grab a couple of movies that you never heard of at the library and want to know more about them than just what’s on the back cover of the packaging!
