I don't necessarily have a favorite director,
but every Guillermo Del Toro movie I've seen, I have been absolutely been amazed by. Pan's Labyrinth was my introduction to Guillermo Del Toro; I saw it in my 11th grade Spanish 4 class and at first, it freaked me the hell out. I then saw Mama and realized Guillermo Del Toro was involved (executive producer) and they kind of had the same sort of ending (come to think of it every Guillermo Del Toro has sort of the same ending). I've recently re-watched Pan's Labyrinth and I think that because I wasn't in a class being forced to watch it, I enjoyed it more, even though a lot of the parts still did/does still freak me out.
