I really liked Elfen Lied, as effed up as it was. I don't think I'd recommend it to anyone because of how wrong some things are (stuff like, I dunno, seeing
little girls naked
is kinda sort of very icky), but yeah. It was a good watch and I recall one scene vividly that really upset me.
[spoiler]The part where the puppy gets beaten to death in front of Lucy by two boys who picked on her, when she was a little girl.[/spoiler] I was shocked to see something like that, though there are other shocking moments, of course. I'd have to watch it again since I blocked most of it out. Either that or I plum forgot it. :<
