13 Assassins (2010)
Chosen by me as I like to go to the cinema a lot
Compared to the lunacy of some of Miike's movies 13 Assassins is a straight tame affair. But it still has people exploded into a shower if blood, bulls set on fire and stampeding through a bunch of soldiers (not brilliantly rendered but fun anyway), a quadruple amputee with her tongue cut out and other wackiness (*spoiler warning* someone survives a seemingly fatal wound which is jokingly dismissed).
It starts with a fairly slow build of the assassins forming together (we have only 12 for quite a while) before coming to a bloody 40 plus minutes of battle.
It's does a reasonable job of giving most of the characters hooks to recall them by for the final, sometimes confusing fight but can't quite juggle them all effectively, especially with time having to be spent on the interesting bad guys aswell.
It's a compelling, visually arresting film, well worth seeking out.
