Worse than I remembered it
I first saw this movie when it came out in 2013, and from my memory the movie seemed all over the place.
It starts off well. After what seems like a few minutes of introducing the characters, the movie goes into full throttle mode with some good action and crazy zombies.
But soon after, it's all downhill and the movie just comes down to a very boring military exercise. There's a lot of talk, and by about 55 minutes into it I just gave up. There are some action sequences but it's shot in the dark and I could hardly see anything.
Life's too short to waste any more time on this movie, particularly after I looked on the IMDb, I rated it 5/10. I think I was being generous.
I can't waste any more time on it. It just didn't grab my attention.
