Yeah, ok, just watched Mind game. It's absolutely the most insane anime I've ever watched.
I'll give you the basic plot: While meeting an old flame, a guy gets shot in the butt, goes to heaven, comes back, steals a yakuza's car, gets involved in one of the funniest car chases ever, and drives off a bridge into a whale.
At this point the film starts getting weird.
The animation is.... interesting. The art design is like nothing I've ever seen before, and every now and then the art lapses into completely different styles, there's a lot of rotoscoping and there's even one scene that's done in oil painting.
The characters are funny, the plot and development is interesting, the ending scene is monumentally awesome.
There is nothing I have to say apart from watch this, if only for the girl who's wearing a strap-on that's actually a balloon full of baby dolls.
