I mean, top 100, really??

Maybe you didn't see it in the theatre when it came out because you weren't born yet? Thus you would not undertand most of the biting satire and references to U.S. culture in it. And if so, there's nothing wrong with that. But it is a satire of its time. Not meant to be laugh out loud funny. It's also a drama including a suicide attempt. And it's a black comedy. If you are too young to understand that, here is what a black comedy is: Black comedy, also known as dark comedy, morbid humor, gallows humor, or dark humor, is a style of comedy that makes light of subject matter that is generally considered taboo, particularly subjects that are normally considered serious or painful to discuss.

I put it in my top five movies of all time.
