So I just finished watching Elfen Lied. It's good! At least, I really liked it. I suppose I'm a sucker for happy endings, even if dozens of bad guys have to get dismembered in the process. If you can stomach the graphic violence (i.e. limbs getting ripped off, severed bones, etc.) you should definitely watch it. The anime itself is licensed in English, but the manga is not; so if you want something you can ethically (though the legality is questionable) download, you can read the manga version (note: I haven't read the manga, so I don't know how it compares to the anime). There's also an anime trailer available which isn't as graphic as the series itself.
Incidentally, my new desktop.
