Guillermo Del Toro.
The two movies of his that I've seen were truly amazing.
Pan's Labyrinth was a great twist on old fairy tales and it had an unbelievably good story, well developed characters, and the soundtrack was amazing. 10/10
The Orphanage was a really good thriller with a great backstory and again Del Toro succeeds at fully developing characters, which is something that isn't seen often these days. Soundtrack not that great really. 9.4/10
And just for some reason, the fact that both were in Spanish was a great thing. Both are rated R.
