I'm irritated from the beginning. The name makes it sound like some sort of revelation, and humanity is going to battle for it's own survival....
But, according to the established canon, this takes place before Alien 79, and those people had clearly never encountered aliens before. And we already saw xenomorphs on earth even earlier, in the Antarctica predator pyramid. And again in the Pac NW in AvP 2. So this is more secret alien shit, and who cares. I already saw this show.
