If you haven't seen "The Suicide Club" and you are into extreme cinema, then I think you should go to your netflick and put it on your list. It is an incredibly oddball film. In Japan, Suicide becomes a group sport. Whole classes kill themselves, leaving cops holdng the bag and wondering why. The bag, by the way, is literal, and holds skin samples of all the suicides. So, who is behind it and why? Well, it's not a spoiler to say to just watch the film and enjoy the funkiness and don't worry about logic.
It's also a musical!
