I attempt to only reviews stuff that I like, and as such, this will be my first "under 4 star" review. But I couldn't help it. I amazed that this many people think so highly of this movie.
To start with, I am, for the most part, a fan of Tom Green. His material is stupid and designed to shock, but it is legitimately funny. Why? Simply for the shock factor. He is funny because people have no idea who he is and what is happening to them. He is funny based on the unscripted reactions that he gets.
This is where this movie goes horribly wrong. Tom Green cannot be funny in this setting. He is doing the same stuff, but without that reaction it is nothing. It goes from comedy to a man shaking a horse penis for no reason. I cannot say that I didn't find some things funny, but those things lasted about 5 minutes total. The rest was downright awful, and desperate. "Look at me shake a horse penis, hahahaha, laugh you.... LAUGH!" No, this doesn't work.
Tom Green could have made something like his "Japanese (I forget the rest of the name) Special." That was funny. Scripted Tom Green, however, just doesn't work. And it is because of this that I am forced to put this movie at the bottom of the bottom of worst movies ever made.
