Haven't read the books.

Just finished season 2 and yes, it may not be quite as clever as the first series and it certainly felt slower but overall I thought it wasn't too bad. There's a lot going on and sometimes you feel a bit lost but it does explain itself as the story progresses and results in setting up a potentially mental third season. I just hope it gets the finances to give it a good go.

Given I've heard it avoids a lot of the book I am certainly tempted to give it a read.
