This show was excellent right up until they killed off Kelly Reilly's character in a failed attempt to be something like Game Of Thrones. It failed. Reilly's character together with the other lead made the show fantastic. In my opinion, they killed the show when they killed her.
Game of Thrones this show is not, but it was good enough until it became obvious they tried to make it into something it's not.
Looks like Amazon agreed. I don't blame Amazon for dropping the show right then and there. I for one am not even interested in watching if further. I'd rather do laundry or rake the yard.
