Yes, I agree on not knowing how they can get more than one season out of it. Even its title is wrapped up into the cult. Not sure how far behind you are from us but I think only three episodes have aired so far over here.
Does it ever bother you that EVERYBODY is beautiful on these big American shows? Ok, so maybe the cop who became a follower was the one exception but the University kids are all good looking, the killer is good looking, the wife is gorgeous etc. I know, I know....that is American tv. But, I sometimes (often) think it would be so much more realistic if they had diversity in looks!
