I've seen this movie 3 or 4 times now and I still love its zany crazy artistic atmosphere. The screenplay is written by Neil Gaiman and the set designs/drawings in the film are from/influenced by Dave McKean and Ian Miller (more Dave McKean than the latter from what I could tell by the styles). SO BEAUTIFUL. And creepy. Ugh, jealousy.
Seriously though, watch it. It's an awesome trip with a great moral to it.
