Agreed, Spirited Away is most definitely not a "WTF?" kind of movie (unless you're an idiot).
It's a nice little straightforward Alice-in-Wonderland-esque tale about a precocious young girl getting inadvertantly transported to a fantasy world and her struggle to come to terms with how things work and how to get back to her own world...although unlike Alice in Wonderland, Chihiro/Sen manages to bring some semblance of social change to the screwed-up world she ends up in.
It's a very nice movie, and if you didn't enjoy it, I'm afraid I'll have to bite open your throat and spit your blood into the air like a fountain.
