I didn't read the book so my opinion is solely based on the tv show. And the show is bad in so many ways. However let's start with the good stuff.
Ólafur Darri Ólafsson is amazing as Bing, Zachary is fine but that is it. Soundtrack is above average and photography is great. That is all.
The biggest problem is character development. It's poorly written. Vic and Manx are so damn boring that I simply couldn't care if anything happened to them.
Maggie's is probably the most stupid thing I've seen in television and the bad acting made me wish the character was dead after OD. Her scene running from the car almost gave me cancer.
I really think it was a waste of time, last 2 episodes was a sequence of disappointments.
Not watching any new seasons for sure. I rather just have a chat with someone who loves the book and let them tell me how it ends.
