I only started watching this after season 2 ended and a friend recommended it to me. Watched it weekly after that. What a ride.
But yeah, the biggest problem is the slow start. The "Monster of the Week" episodes do feel different enough to be interesting, but aside for a few small scenes, the first 6 episodes are just that: Monster of the Week episodes. Episode 7 is the first episode that shows that there is actually more going on. Imo, this is where the show really starts.
I would really recommend everyone to watch these 7 episodes, and if they really feel nothing by this point in time, they should drop it, imo. But if you stick with it, the show only becomes more crazy as it goes on.
