Hey, I got some comics … erm… graphic novels for you I’ll skip the obvious ones:
Powers, Alias - both by Brian Micheal Bendis. I hate superhero books, but I love these. Powers is a really good, very dark comedy / crime noir book. Alias is about a Private Investigator who just happens to exist in the Marvel Universe. Powers is the better of the two.
Goldfish, Jinx, Torso - All Bendis again, but these are his earliest books. He also drew these comics, and it’s a shame he stopped drawing his own stuff. His art kicks ass.
Mr. Blank - One of the most awesome things I’ve ever read. Smart, funny, loaded with action and interesting characters… I’ve read through it a couple dozen times, and every time I do I can’t help but wonder how the creator, Chris Hicks, has managed to elude fame and fortune. If you dig Bone, then this is right up you alley. It’s kinda old, tho… the collection came out in 2000, so finding a copy might be difficult… worth it, tho…
The Flight Anthologies - there are 5 of them now. All of them good. Maybe lighter reading than you’re looking for… they aren’t exactly mind-imploding tales of sophistication, but are a very good showcase of young talent.
Maus - You might have read it already, but I have to add it to just about every list of comics, as it’s THE BEST comic ever made. No question about it.
And if you really want to read some interesting crap - if you’ve not already - check out Scott McCloud’s “Reading Comics”. It’s written in comicbook format, and the content is basically about comics, but a ton of it can be applied directly to just about any other multimedia or artform that exists. It’s less about comics, really, and more about storytelling and how people interpret things. And art.
