I still haven't finished Watchmen and I haven't read his other works either, but I did heard of Lost Girls and some of the comments it has, and like what you said, if it was considered art, porn or even art porn. Can't say much except that I hope to read the book someday (once i'm 18 atleast) and see what I can formulate. As for Alan Moore, I can see the guy in the line of Kubrick as a batshit insane, but genious of what he does.
