Art is such a meaningless term. It's only when it comes to things that don't really have anything to do with the actual comics that it's a concern. Yes, comics are art, so that the state can give grants to cartoonists. Yes, it's art, so that libraries will put comics on their shelves. Yes, it's art, so that comics will be reviewed in newspapers. But when you're sitting with a comic in your hands, reading, is it art or not? Who cares?
