Someone has to say it: this show is terrible. Seriously, is the worse. It is barely american, surely is not horror, and has not story at all.
Every season is a bad mix of common fears, bad written characters, inconsistent plot, and every season is culminating in a absolutely "WTF!" finale, where all the elements used become suddendly useless. "Roanoke" and "Cult" were the best written, but still instead of create something truly scary and admonishing, writers prefer to dissolve everything in an useless, non-catharthic, not scary at at all nonsense ending.
Actors are pretty good, expecially Jessica Lange and Kathy Bathes, and surprisingly Lady Gaga is not bad at all. Photography is interesting, curated and harmonious, but that's all. AHS is a show of appearance, with no substance at all.
Finally I said it.
