"How Guillermo del Toro Deals With Trauma"
I highly recommend seeing BOTH "El espinazo del diablo" ("The Devil's Backbone") AND "El laberinto del fauno" ("Pan's Labyrinth") and THEN watching the analysis below, which is quite good. The two movies are meant to be seen together; start with "El espinazo del diablo". SPOILER ALERT: Watch the movies FIRST.
