Yatta!
Hehe, this completely absurd movie reminded me of "Yatta!" a lot, both in style, kind of humor and the whole Japanese-culture thing. I enjoyed "Yatta!" a lot, but I think I like this one even more. The little "subtitles" amused me pretty much, since I always try finding things like that in songs in Japanese I listen to. The funny thng is that I actually have this song on my computer (Shiny Collection by Gravitation, for those who are curious), and it made me remember the song by heart! Very funny! The absurd humor is also pretty Monty Python-esque, and, just for that, it has to be good.
I think of this entertaining movie each time I listen to the actual song! =)
