I haven't seen any of the episodes, but the trailers look OK. I don't know, this just doesn't grab me. I haven't watched an episode of Hannibal or Bates Motel either and I doubt I will. Not that they all turn me off, they just don't seem like something I'd stay interested enough in to see the season or series out.
I like AHS just because I want to see what they do next. The Name Game episode last season was a really good one, and the fact that they change things up every season keeps it kind of interesting. It's definitely no Walking Dead, not by a long shot.
