I think a lot of people wanted to watch the Human Centipede movie because they heard that it was pretty sick. Too bad it was lacking in story.

"A Serbian Movie" is about 500 times sicker; but that is offset by the story which is actually quite thought provoking. It's a movie which I would recommend trying to see through until the end at least once. Although most critique reviews suggest that very few people are able to make it through the whole movie because it's so sick.

You might have to watch it online as most countries have banned it from sale.
