Elfen Lied is up there on my list of must see anime. I wouldn't really say it's Chobits (sp?) on crack. More like Chobits that was on drugs, gasses, etc. but can't find it any more so it goes kinda phycho and kills people.
I like this series. Nice and bloody with some story (if you call it that). But I like little kids on killing sprees... But Elfen Lied isn't just blood, blood, and more blood. There are some cute moments. Sometimes there are times that are so depresing and makes you love the little killers.
But then agen, I hated Chobits so...yeah... ^^
