Not Netflix, but on Hulu Plus is "The Booth at the End" which is a cool miniseries. It's about a guy in a diner people go to when they need things. They ask for something, anything, and he tells him what he needs them to do in order for what they want to come true. Sometimes he asks them to do something helpful for other people, sometimes he asks people to do terrible things. The story involves about 8 people who go to him, and their stories become intertwined at times and at others remain entirely separate. It remains ambiguous even through the end of what he knows, or how he does what he does, and it's best that way.
