I finished it last week. I enjoyed it, but I feel like it ran out of steam a little. There were quite a lot of sudden deaths, which felt like they were trying to clear the decks for the next season.
I thought the whole storyline of Mason and his baby was stretching it a little too much, but I did like how Wendy is stepping up to the plate, just as Marty is starting to crack up and lose control.
My favourite character is probably Ruthie - I definitely had a lot of empathy for her, trying to do right by her cousins, and dealing with her scumbag father.
