I have heard that it does have a high levels of fucked-uppedness. I thought Ichi the Killer was pretty messed up too.

I was gonna watch Battle Royale weeks ago, but then it disappeared from the on demand, which saddened me. But maybe it might've been too gory for me...

I did watch a movie this morning called Murder by Death. In a word: hilarious. It's a spoof of popular murder mystery/detective films and books. It is very funny, and the dialogue was great. If you need a pick me up, watch it.
