Sure, and Jack Kirby drew weird knees. There's a lot more going on in Quitely's work than the surface rendering. "His people are ugly" is the most frequent negative complaint I see about his work and it's also - forgive me - the most shallow. Quitely's work is utterly fascinating to me because he has an almost unparalleled ability to create a sense of life in his drawings - from his meticulous design and creation of environments that always evoke the sense that there is a thriving, living world that continues beyond the panel borders, through to the subtle gesture and expressive body language of his characters that make them feel sincere and human rather than posed mannequins. I marvel at his dramatic compositions, at his economy of storytelling and mastery of pacing and continuity, and at his ability to use the comics form in clever, inventive ways that haven't been seen or attempted since Eisner (We3 had some startlingly inventive and revolutionary page structures and should have been a wake-up call to comic artists, and sadly it remains unchallenged). And he manages to do all this with a drawing style that is uniquely, idiosyncratically his own.
I'll take that over "pretty" faces any day.
