It reminded me of Alien

Rating: 10/10 (17 April 2018)

It didn't put a ten because it deserves an Oscar. I did it because I loved it.
Spoilers:
People complain about the stupid things the characters did, like the pregnancy. And I think it is a bad move because they already have children to protect. However, what do you expect? this people have no hope, no one will save them and they want to enjoy life instead of just spending the rest of their lives doing nothing because of the fear.
Also, to the person that complains about the lack of backstory, movies like Alien didn't have backstory either until the prequels. They just found the monster and it started killing them one by one.
Regarding the sacrifice, you don't take your time to evaluate all the options when the people you love is seconds to get killed.
The military part is tricky, it sounds strange they couldn't against the creatures, however we don't know how many creatures there are, there were just 3 here. We don't know if they have more ways to attack, how strong they are (they can break through the silo, they might be able to break through a tank or a bunker), nor if they can survive radiation or explosions. And we don't know if the military really lose or if the people in the movie just lost contact with the world.
The ending is not faulty as they say, the creature has an impenetrable armor but it is only in the outside and his mouth was open.
