I enjoyed it, probably better than season 2 actually.
First, they hit the ground running. There's maybe 2 episodes of build-up then it's just pure action for the remainder of the series. I'm OK with this because we've had 2 seasons of slow build-up.. do we really need to spend 5 or 6 episodes trying to figure out what's going on.. again? No.
The characters have also grown quite a bit and it's fun just watching them do whatever. Sure a few aspects of the plot are completely unbelievable to the point of being ridiculous but it's a show about monsters from another dimension, I'm not going to worry about it too much.
Bottom line.. had a lot of fun with this, definitely the best thing on Netflix.
