What the %@$* do you mean kinda? S-Cry-ed is amazing.

By the way, you forgot Vandread, Shootfighter, and a few others I can't remember. Oh yeah, and Voltron.

S-Cry-ed's plot can fade in and out, but there is so much in the way of character development and underlying messages.

Shootfighter is kind of short, there are only 3 episodes, but its definately one of my favorites.

Although its not one of my personal favorites, Voltron is a classic, so it has to count for something.

I'll add some new stuff to the list. For those of you that don't keep up with the newer releases.

Black Blood Brothers
Busou Renkin
D.Gray-man
Deathnote
Fate, Stay, Night
Le Chevalier D'Eon
KIBA

I haven't looked into this. But I don't think it's all out yet. So you might just have to wait to watch the rest.
