I can't see Netflix axing all those other shows, but keeping this and Jessica Jones.
But yeah, I liked this season a whole lot. I also think season 1 was better, as that was all about a broken man with PTSD going on a rampage and then realizing he had a problem.
Season 2 basically undoes the ending of season one (dude going to a group to work out his issues), and basically just says Frank is a killing machine end of story.
Still great though, and a satisfying swan song. I even liked the story arc with Pilgrim, although it reminded me somewhat of Bushmaster.
