I figured out that this edition of AHS is Ryan Murphy and company trying to "M. Night" fans of the show this year. They have very cleverly "dropped and planted" various red herrings and clues, (both on and off screen). I've read some interviews and Murphy and others say "don't even try to figure it out, you won't" and "just when you think you know what's going on, you'll be blown away at the change".
So I guess we have to decide if we are smarter than they are. As for fast changes in the story, some of that can be attributed to the fact it's only 8 episodes this year. Another noticeable thing is the secrecy of the project and no advertising from FOX almost up until the premiere. There are a few hints:
1) One week before Roanoke started, they premiered Lady Gaga's 1st new song from her new album on Scream Queens. Gaga is almost unrecognizable in AHS. She doesn't get screen credit until 4th episode. The name of Gaga's new song is "Perfect Illusion". (Then her next semi-country single is released within a week or two of "Illusion"...seems kind of fast but could be marketing).
2) There are two posters for this season, with a similar clue in both. The bumper poster is a large tree, very wide, showing the roots spreading underground. The online poster shows a woman, (can't tell who it is), holding a rosary but it has a stick figure of a man hanging where the crucifix should be that actually resembles the roots of the tree from the first poster.
3) As several people have previously mentioned, this whole "dramatic re-enactment" should technically be everything we are seeing, the couple, the murders, all the previous owners, Cricket...if you believe that then the only thing that's real are the interviews, the uber driver interview, the producer's voice...
I'm sure there are more I have missed and I don't know if I should go back and re-watch to find more clues. One thing I'm sure of is the wig masters and hair people for this must have busted their butts. For all the people that love or hate the Murphy "machine", I am glad how he continues to hire openly gay actors and also, it seems, very gay friendly actors, crew, etc. If I was in LA I would certainly appreciate being in his "gay talent pool"; he must have at least 60-70 actors that are openly gay that he helped start their careers and/or continues to employ. I was looking at the cast for AHS/Roanoke, and although I haven't been able to recognize him yet, Chaz Bono is even in the cast.
Lastly, even though I've only seen it from re-runs, how can you really not appreciate AHS when they use Shirley Jones, David Cassidy and Partridge Family singing "I Can Feel Your Heartbeat"? Is this a clue too??
