Y is good because it has everything. Ninjas, lesbians, monkies, explosions; how can you lose?
Transmetropolitan is fucking amazing. Most of Warren Ellis' work is really cool to read. Planetary, Global Frequency, etc.
I really like the Ultimates line, though I am quite pissed at what they did to Deadpool in Spider-Man. Though I gotta love Samuel Jackson as Nick Fury, and the varying character flaws every character has. It keeps things interesting.
I have read the first forty issues of Hellblazer, and I am not impressed. Is it worth continuing? Can I fast forward a bit? I'm really, really enjoying Lucifer and the Sandman, though. I like Constantine, just not in his own comic.
Rising Stars is another good read, as it was created by the Babylon 5 guy.
Kingdom and Kingdom Come are really good.
After reading a variety of Alan Moore's works, I understand why he is pissed at DC at completely screwing his comics up. LXG, for example. I like the V for Vendetta adaptation, but Moore's a schtickler for that type of thing. It does make me worried that they'll screw up the Watchmen, which is my favourite work of his.
