Don't watch this move right after you eat something. The super shaky camera work could make you sick. 5 minutes into the movie I could not bear it. Just too uncomfortable.
The story line is easy and straightforward: people try to stay alive after some sort of apocalypse.
What is missing from the movie is the horror and the family dynamics. You either make the move very scary or you focus on the family and the bonding. Or make both the focus. However, this movie does not have enough either. Turns out the movie becomes boring and losing focus. So people can easily predict what's to come in the next 3 minutes.
It could be much better if they add some mysteries to the creatures. What causes the apocalypse is not that important to me.
