A waste of 2 hours. The protagonist is a very fit, cheating yet faithful, ex-army biologist. Most of the time she behaves like a dumb girl. The concept has so many plot whole. Some things such as multiple organ failure does not even make sense. Lena says, " Its due to radioactivity, maybe a virus". How does radioactivity and virus inter relate? Secondly, they don't show what she eats, or how her memory is erased. And the alien, though, indestructible by a grenade, got burned by fire. I mean, he didn't even know how to extinguish fire. Also US army does not have drones or machines. They are so poor that they didn't even send a car with them. Girl physicist and psychologist are handling guns like toys. How does that happen? It takes years of practice to learn this craft. All in all, don't watch it. Its a complete waste of time
