Borat is one of the flat-out funniest movies I have ever seen. I was laughing the entire time. Almost every scene is one of those memorable ones that you can recall when this movie is brought up in conversation. What separates Borat from all the other "dumb" comedies to come out since time immemorial is that the funniest parts aren't scripted. He interviews people to get their (ludicrous) opinions, and these people and their viewpoints are real. It's horrifying to realize what kind of people live in our country. On a side note, the movie is extremely well-edited; no joke goes on for too long.
