Re: /slides in
Oh, don't worry, I think it's weird, too. I don't usually join in on these things. Really, I'm probably not any more obsessed than I am with my favorite author. Scratch that. I preorder all of her stuff and am terribly sad when it's delayed (aaargh, Pegasus sequel, come oooon), so that's probably more obsessed. I just feel like the author's more justifiable.
I have Spirited Away! Also Ponyo, Kiki's Delivery Service, and Totoro. I used to have Princess Mononoke, but it was on VHS; need to get the DVD copy. And I've seen Arriety. But I know I need to check out Castle in the Sky and now The Cat Returns. I also haven't checked out Tales from Earthsea, but I have mixed feelings about that anyway. Really liked the first two books, disappointed in the later ones, and can't decide if the author's ambivalence for the movie is bad or not.
Mononoke might be one for you to check out if you haven't.
