What makes this series so great are 4 things:
+ intriguing plot that takes its time to build up, but never disappoints
+ moral questions and dilemma that make you think about society, civilization, politics and life in general
+ very well written characters that stay true to themselves until the very end
+ incredible acting and commitment from everyone involved

Season 2 was faster paced than season 1. I was constantly on the edge of my seat. They didn't waste their time to tell this epic tale. Hopefully we will get a season 3.
