isn't really a serial killer show, and its premise is quite different to and much more complicated than that of The Following
is about a TV show about a cult leader with a following of brainwashed minions who do his bidding. This TV show in turn has a rabid cult following of fans. When real life starts to imitate the TV show there's an open question as to whether it's a case of crazed fans playing copycat or whether the show has some kind of supernatural effect on reality. Robert Knepper is playing an actor named Roger Reeves who plays Billy Grimm, the cult leader, on the TV show.
