Well, graphic novels at least.
I suppose it might be hard to ignore Watchmen, 300, Sin City, etc., even for Science Fiction snobs.
Besides, why should there be such a thing as S.F. snobs. (And believe me, they exist....) Didn't they suffer from that same attitude for a generation?
Lot's of Mom's think it O.K. now to read S.F. and Fantasy.
Next.... broadening of the minds (or dumbing down of America, depending on which camp you inhabit) .........comics!
Quit playing video games, son! Read a good comic!
