In Japan, they have 'New Year's' movies, from what I understand, which are movies designed to essentially make the audience go home feeling all warm inside. Miike was asked to do one of these movies, and this was the result.
If you've ever wanted to watch a weird little music that is oddly every bit as happy as its title, something with claymation, fun songs, and a very macabre plot turned on its ear, look no further than Takashi Miike's joyous Happiness of the Katakuris.
This movie is so great, I had to make an alternate ending for my Takashi Miike tribute and would like to share that with you now.

If the charm of the above link appeals to you, go for it. It's worth it.
