This is sort of a strange reply. You don’t have to spend any time on art at all really. For many people, the more they can spend time enjoying the art they like, the better. If you don’t like the art, that’s one thing, but if you do like it, why must it be shorter?

The video game community is often pretty explicit about this. They want their favorite games to be longer, not shorter, because they want to spend more time enjoying it. I don’t think it’s so strange that people may apply the same mentality, to books, movies, etc as well.
