First, I need to say that most comic book artists are not hacks, there are many great talents...

To answer your question, Robert Crumb didn't just copy someone else's idea or style, as a hack would do.

Instead he made his art his own, taking his personal view and thoughts of the world and creating a unique style of art. His ability to draw, create characters and stories - humor and pathos, and hotness is amazing - we are privileged. And this came about because he is passionate about his work, and dedicated his life to honing his craft and art.

It's not that other comic book artists of his generation are untalented, many are real artists, too. It's just that his style was just more appreciated, more likable, or just more appealing than other artists. His audience went from the underground to mainstream - he is good. Obviously I like his work, thus biased, but many agree he is most definitely talented.

Artists who outlet all their emotions ( and intellect) through their work are going to be appreciated...

I love good film biographies of artists from Rembrandt to Georgia O'Keefe to Robert Crumb. I enjoyed the mainstream film about his life and wished I owned more of his work. Thankfully, he is well published.

I like Mr. Natural and Flakey Foont, Fritz the cat was great, Zap Comix were classics! But how about a cheer for Robert Crumb's representations of himself...
