Ok, so I just got done watching Ichi The Killer and despite being one of the most enjoyably grotesque films I've ever seen, I don't get the ending at all. It's like some sort of Japanese David Lynch "Hey fuck you for watching my movie" moment where I don't even know if the rest of the movie even happened. I'm probably going to sit awake and ponder just how any of that was supposed to tie into the rest of the film. It will most likely end with tears. And drinking. Mostly tears (drinking).
