Guess I'm alone but I thought the finale was great. Didn't see a few things coming which I dug.
Asylum is definitely the best of the three. I would rate the first season as my favorite if the ending wasn't so fucking atrociously shit
I'd love to see a carnival story... although yeah
Carnivale has already done it and I doubt very much it would be topped.
A Manson style cult would be interesting too.
