This has become a classic because it's the ultimate chick flick: it shows how mean girls can be towards each other. It's a necessary message embedded in a funny, silly film with some really good actors, such as a young Rachel McAdams, although I also have to admit I'm a little biased because it was a part of my own coming of age - I grew up wearing pink on Wednesdays. It's valid entertainment IMO.
