Every now and then you see a movie that has so many elements that you keep thinking and talking about it, and can't get out of your mind. Makes you think.
I don't want to hype it, but it has suspense, drama, strong character relationships, this film keeps you thinking by wondering about "what would I do?".
This film makes you wonder what would happen to average modern people (not scientists, politicians, etc...) if they were hit not two thousand years ago, but now in present time with something like brain-dead epidemics or even worldwide pandemy, there is no easy and ready black and white clear answer.
It's a must see, when it comes out in cinemas if you are looking for an intelligent horror - thriller, this is it.
If you are looking for a human realistically plausible drama, this is it too.
