Elfen lied... It was awesome..
I've watched it all, with an anime loving friends, and 2 non-anime-watchers.
we all enjoyed it (since it's awesome), but during watching, the non watchers (more like non-believers! phaa!) kept asking us if this gets us turned on..
I hated all that fanservice, they kill puppies in the show, they torment kids and put them in research facilities, it doesn't need fanservice.
