Well. What have we here? Probably some stuff that could fit elsewhere, like family films, or action/adventure, or comic book movies, or science fiction, or giant monsters, or... meh, any number of things, I dunno. Even dramas or comedies. So, what constitutes fantasy? Could be simple sword & sorcery type stuff, or anything that just seems magical, or unrealistic in some way. I mean, stuff that just couldn't really happen.... or whatever.
