'American Horror Story' is unlike anything else on television. Created by Ryan Murphy and Brad Falchuk, the show has been pushing the boundaries of horror since it started. Each season has different characters and settings, yet (mostly) the same actors. Season one follows an estranged family when they move into the murder house, season two shows the brutality of an insane asylum in the 1960s, season three explores a school for witches, and season three is about a freakshow in the 1950s.
