Never did this show before, just did all 4 season plus new ones. I like it more than 1rst season but I feel a bit like "24" syndrome with it. You can only go so long with this premise or it gets boring. They need to win at some point and that will end the show. I would say they should call it in season 6 and give way to a prequel or sequel and stop the weekly almost die/almost win, which is getting annoying.
I have coined a new phrase from this show, I call it my "falling skies" hug. You know where you were supposed to be dead again and I get you back again, and I give you a huge hug again and say how happy I am you are alive....again? yeah, that one. You could almost make a drinking game out of it.
