This movie has my favorite IMDB user review of all time.

It is by someone named Selena who watched the film with her mother.
Her final paragraph is what made her review so great. -

"My opinion of this movie is that it was good. I do recommend it but not one for the younger ones to see or for people that are homophobic or have problems with cannibals."

So one must conclude that this is a great movie as long as you have no problems with cannibals. Why did Karl Pilkington come to my mind when I read that statement.
