El laberinto del fauno (Pan's Labyrinth)
It's hard to say if I would recommend it. Part dark fairy tale, part dreary reality, it's certainly creative, and beautifully done. And it has impact... but, it was literally somewhat painful to sit through, because of some of the scenes... believe it or not, none of the scenes that were unbearable were the ones containing grotesque monsters like the one above.
Anyway, the movie was definitely amazing enough for me to feel like it deserves a shout out.
