Assuming the question is high-quality and on-topic, should questions about graphic novels/comic books be on-topic for this site?

On one hand, comic-books are books just like any other books. On the other hand, because of the nature of comic books they're much more likely to be about Sci-Fi topics, like spaceships, superheros, and magic, so they might be better on Scifi.SE. (Although that doesn't make them off-topic per se)

Should we allow questions about comic-books?
