Actually Pan's Labyrinth kind of has an up ending. It is a pretty good movie, and the DVD does actually have an English dub of the film, not sure how good it is though.
I have yet to see Devil's Backbone. I like Del Toro. I am glade he is doing The Hobbit, though I really hope they match PJ's The Lord of the Rings to a fair degree. But even if it doesn't, it is not that big of a deal, in many ways the actual book The Hobbit has a completely different tone and feel to it from LOTRs.
