The art is fine, comic books as a medium are robust, they can be fine examples of narrative, of dialogue, of art, or they can be designed to capture a feel, in an attempt to evoke this in the audience.
Not liking the art is one thing, it's doubtful that there are "better" artists, or that deriding the artist and artwork say anything about the art itself, whereas it says a great deal about those who protest so loudly!
I've said it many times and I'll say it again. Marco Rudy is the pinnacle of comic book artists. His mastery of inventive layouts blows me away, and he's one of the few artists who completely legitimize comics as a form of media; doing things no other form could do.
I agree with you 100%. He is absolutely my favorite comic book artist right now and I think it's ridiculous that it's taken so long for him to be given an ongoing.
