Here's all I've seen so far: Neon Genesis Evangelion (original series and movies) Gurren Lagann Kill La Kill Attack on Titan Blue Exorcist (surprisingly good choice, Toonami) Darker Than Black Ghost in the Shell Black Lagoon (and Roberta's Blood Trail) Trigun Hellsing Ultimate Cowboy Bebop Space Dandy I'm still breaking into anime so I haven't seen much yet, but I recommend all of these.
