I just finally found time to watch this earlier today, and I was very impressed, though I knew I would be! Ryan Murphy is easily one of my favorite television writer/creators, so I knew I would be tuning in when I found out this was a production of his.
I agree with Gothick about some parts of it being a little uneven, however it is smartly written and edited so if you aren't paying attention you're going to begin to wonder why some characters are in certain places when two seconds before they were somewhere else. I like that it's not dumbed down for the audience, i.e. following a character through the hallway into another room where they talk to another character. Instead they cut straight to this next conversation. And the editing is somewhat jumpy, which might cause some confusion.
The only real gripe I have about anything in the show is Connie Britton. I LOVED her in Friday Night Lights, and genuinely think she is a good actress, but I thought the fight between her character and McDermott's character was dramatic and engaging, but Britton just didn't quite pull it off for me. She fell somewhat flat with her performance.
Otherwise, I'm intrigued to find out who the Rubber Man is, and just what the deal is with that Maid!
