yeah, it WAS really weird. i wish more weird things would come out of japan, honestly, and not just teenage-girl-getting-fucked-by-tentacles weird, either. there's too much of that kind of weird! people champion boring shit like PAPRIKA as being indicative of japan being at the top of the animation world, but i watched that shit and HIGH PRODUCTION VALUES but it was pretty boring. the sex scene on the boat in the whale was one of the coolest pieces of animation i've ever seen, though. that was maybe my fave part of the movie as far as visual stuff goes.
unfortunately kemonozume doesn't do as much in the ways of weird bells and whistles but the animation style is still atypical (often a complete lack of shading, like in mindgame). if you look at the wiki it shows character portraits that give you a pretty good idea of the style.
samurai champloo is OKAY i guess. the first episode was actually pretty good but after that it tapered off a lot. it's got STYLE but there's very little substance and the characters are pretty wooden and uninteresting, which ultimately made me not really want to finish the series. also it is very meandering and episodic and doesn't really feel like it's going anywhere. bebop was this way too, to some extent, but the subplots and characters were all a lot better so you actually gave a shit what was going on. it's sort of disappointing because i liked cowboy bebop a lot and it was kind of lauded as being the next version of that (samurais and hiphop instead of space cowboys and jazz!), but where bebop was style with some amount of substance attached, champloo is mostly just style. there is this one ep in the middle of the series tho where the cleaner looking dude falls in love with a prostitute and it was pretty good! it's not really a series worth watching, though.
