Season 1 was bearable, but Season 2 is seriously dragged. The only highlight was the Nikolai arc (mainly because of the actor). The whole arc about the elder son of bill Boone and the mother of the guy he kills is completely useless. I know because I fast-forwarded through all of it and I don't think I missed anything.
Story is very weak, acting is horrible (except for few), and the entertainment value is super-boring. My recommendation is to watch it at 1.5x speed and skip through majority of the filler stuff because it is so, so, boring. I had higher hopes.
I really hope Season 3, if there is one, is better than this.
