This show isn't going to win any awards, but it is highly entertaining with a delightfully dark vibe and a good dose of suspense. The main problem with the show is that it doesn't really develop the relationships between any of the characters except Ryan and Jed. Other than those two though, it's unclear why any of these people put up with each other. Molly is a useless character who is apparently slavishly chained to Kate as her bf, despite the fact that Kate is a hateful person who sleeps with anything that moves, including an attempt in the first 10 minutes of the show to seduce Ryan, on whom Molly has a crush. Then there's a weird uncle who hates Jed, and Kate who hates Jed as well. For some reason that isn't well explained Jed is still devoted to Kate despite knowing that she hates him.
Basically, the relationships make zero sense and you just have to roll with it for the sake of enjoying the weekly mystery and action, which is really the redeeming grace of the show. The writers know how to amp up the suspense and the creep factor, and that is the mainstay of this show.
