To recap: My Roanoke Nightmare shifts the format of the entire series. Shelby (Lily Rabe) and Matt (André Holland) are a couple who moved into an 18th-century home in the middle of Creeptown, USA, a.k.a. Roanoke, North Carolina, only to find themselves victims of hillbilly torment, Biblical plague, ghost infestation, and a Blair Witchian craft enthusiast. Run-of-the-mill fodder for American Horror Story, except that Murphy and his collaborator Brad Falchuk compose the story like a lesser version of their American Crime Story series.
The "real" Shelby (Lily Rabe) and Matt (André Holland) recall the events as talking heads, while Sarah Paulson and Cuba Gooding Jr. play actors in a filmed re-enactment of their story (that happens to look a lot like a typical AHS episode). The only thing missing are cheap motion effects and a Robert Stack intro and we'd have an episode of Unsolved Mysteries.
