Ya its pretty grim. Its about a girl during WW2 in Spain and she and her widowed mother are going to live with her mother's new husband, who she is pregnant by. Hes an evil sob and does some pretty nasty things to people. Definately not for children.
Anyways the girl ends up being told by woodland nymphs that shes a princess of the underworld and she needs to come home. Has a few tasks she needs to fulfill to do this, and Pan is pretty creepy...never know if hes genuine or up to some trickery.
Its NOT like Lord of the Rings like the hype says...more like Legend was..that misty woodland, magical feel to it. Really pretty good.
If you see it, reply here and see if you interpret the ending as I did.
