Read books by AWers!
Though, yeah, AHS definitely tends to throw a whole lot of stuff out there without thoroughly exploring any of it. The plotline with Patti Lupone's character was a bit random.
But I don't think Coven was anywhere near as random as Asylum was. Which isn't really a criticism of Asylum--it was my favorite season so far. But I liked that Coven tied stuff together a little more.
I liked the finale, even though I was miffed that Misty got the ending that she did.
I agree that Cordelia being the Supreme wasn't a huge surprise. It was satisfying, though.
Also, how did they know that the next Supreme was going to be someone in that one small group? I know the coven was dying out, but it was established that there were other witches around the country who just hadn't come forward or gone to the school. How did they know one of them wasn't the next Supreme?
I also find it interesting that the whole thing about Violet killing people through sex was dropped pretty quickly. I don't think it was referred to again after the pilot, was it? It's like the writers thought it was a neat idea, but realized it didn't really serve a purpose.
Looking forward to 'Freak Show!' Love Angela Bassett's character just based on the trailer.
