I'm pretty pumped cause I loved it but I can't help but feel they finished it off near perfectly, like a well paced film. Shows rarely get that sort of closure and when they do try to force a second season it usually turns into complete garbage. Sort of like season two of Wayward Pines.
One thing I'm not at peace with was when the sheriff sacrifices El to get Will back, felt so out of character for him. I'm also pissed no one seemed to care about her in the other dimension so if season two consists of trying to get her back I'm all for it.
