This is not crap, but it is also far from good

My flatmate left partway through the movie and came back near the end to tell me that he admired my tenacity for getting all the way through it.

It wasn't terrible. Some of the cgi was good and so was the idea. A bigger budget might have allowed for better props and more extras though, which would have made the movie a lot better. It just looked shabby to have the same guy in the same makeup play the role of different zombies along the way.

The guns and equipment were often mismatched and kept switching between characters between scenes as well. Lastly, most movies showing military forces have the actors trained to behave like the military. It just makes them look like they weren't given a plastic gun and told to walk down a dark hallway pretending they were soldiers.

Not a 1/10. But not much more than a 3/10
