I love Bebop, with FLCL close in second. Shamploo I haven't seen much of (I recognised Spike's "voice", though). I can see how Cowboy Bebop and Samurai Shamploo would be brothers, though.
I don't read that many comics. Sure, I may go over some old DC batman comics once and a while, but for the most part I tend to avoid that genre all together. Not to say it's bad, it's just not my cup of tea at the moment.
