I really enjoyed the show, and I found it pretty decent on the second watchthrough as well, although I really didn't care for the actual ending.
Spoiler thoughts:
Show content
Just about all of the "big reveals" like the killer's identity were pretty easily guessable way in advance, and every major character that was even moderately heroic wound up living. In a show that was supposed to subvert horror cliches, it was pretty disappointing to see them play just about everything so straightforwardly - I guess with the exception of what Grace and Zayday did with Hester after the fact, which was to completely ignore all of the proof they'd compiled against her and accept a transparently obvious lie so that the Chanels could get what was coming to them.
Ultimately I really don't know how to feel about it. I wish that it'd been more surprising and pushed the envelope more, since that was what the show was purportedly supposed to be doing the entire time. It also doesn't help that they took out Gigi before we got to see how her villain reveal would've impacted her relationships with Wes and Grace. That arc could've been a goldmine.
