Season 2 is out and there will be a third and final season. The show was apparently conceived as a trilogy so the entire story will definitely be told
I'm gonna have to rewatch season 1 because it was confusing enough at the time, I've forgotten so much in the time since I watched it. I remember that I loved it though despite being lost on who was who in the different time periods most of the time
(was not sold on the apocalyptic future ending but the season 2 trailer has intrigued me to it). But it looks like season 2 is going very 12 Monkeys which can only be a good thing
