The reason people hate on this film
I think the reason people hate on this film so much is that it's too quick for them. By this I mean that the film moves so fast and Leguizamo's performance is so frenetic that they missed most of the jokes and so therefore dismiss the film as not funny. This is actually a very well written film with some hilarious humor (mostly racial albeit) but I think the fact that the film never takes a moment to breathe or even establish itself caused most of the jokes to go over people's heads. I first saw this film when I was probably 12 and have seen it dozens of times since then and literally every time I catch or understand a new joke. This to me is a great comedy because it's consistently funny every time I see it. Not to mention Leguizamo is just plain fun to watch and is at his wacky, high energy, improvisational best here.
That's who you remind me of, an evil Mr. Rogers
