I recently got into the show and just caught up. Really liked season 1, hated season 2 pretty badly, and this season has been entertaining enough but completely lacks the horrifying/disturbing aspect that got me interested in this show to begin with.
It's still decent compared to a lot of TV right now, but I really don't like where they've taken the show. The witch storyline feels too feminine for me to get excited about, and they've replaced horror and disturbing scenes with pure gore. Meh.
Lily Rabe looks kinda weird at times, but for some reason she really does it for me in some scenes. I like the hippie look on her this season especially.
