The Origional Danarchist
I have at least 3 friends obsessed with anime, so I have to argue about this all the time. Anime, as a general rule, is crap. I've seen the stuff on Cartoon Network, I've seen the stuff they used to play on the Sci-Fi channel, and I've seen several videos as well.
Basicaly its just a bunch of horribly-animated action scenes smushed together and tied with a weak (and often nonsensical) plot. In short, its just an excuse for making a film full of sex and violence without putting any effort into it.
At the apogee of horrible anime lies Project A-ko. I cannot rant enough against it. Heres the plot: First it starts out with a crappy storyline about a girl who goes to school with a bunch of weird-ass characters, most of whom have superhuman strength for some odd reason. There's C-ko, a little girl who throws a temper tantrum every 5 minutes (fucking annoying). Then theres B-ko, some bitch with something against A-ko(inovative names, eh?). Then theres some huge behemoth of a schoolgirl who's voice acting gets taken over by Lou Ferrigno whenever she gets pissed. Apparently, theres some mysterious guy whos following around A-ko and C-ko for some mysterious reason. The next half-hour or so is comprised of a long-ass catfight between A-ko and B-ko. Then when no one is looking, C-ko is abducted by aliens (of which the mysterious man is one of). I think they did this because C-ko was their long-lost princess or something. It didn't really make sense, but now we have a 3-mile spaceship hovering above the city, and A-ko and B-ko fighting in mech suits. A-ko breaks off the fight to rescue C-ko, and when in the alien spaceship, she discovers a room full of underwear, relealing the aliens dark secret: they are all female! Even the butt ugly ones with a male figure, deep voice, and a stubbly chin! However, this doesn't really seem to have any impact on the plot, but the whole thing ends with the huge ass spaceship landing on the tallest, thinnest tower imagineable...and it doesn't fall! It just sits there while everyone proceeds with their daily lives as if nothing happened. Oi!
But there are is some 'good' anime. Record of the Lodoss War was kinda cool, but its been years since I've seen it. Dragonball is addictive to watch, maybe because Vegeta is so badass (hehe). This show is best watched with friends, because its fun to make fun of all the cliches and horrible plot development.
But the bottom line is that anime is not worth going out of your way to watch, and getting obsessed with it turns you into something worse than a trekkie.
