I got what the film was going for by the end of the film but, seriously, would've been a lot less frustrating had the film actually told us a bit about what was happening before they decided to hit is over the head with it.
The only thing told from the beginning is that everyone is mute, because of the apocalypse and their sins of speech or something like that. That's all you get. Other than that, it's up to the audience to piece together the, once you figure it out, incredibly simple storyline. And it is just that, a simple film. Nothing note-worthy here. Just some decently staged gory moments, and some decent acting. The ending is incredibly predicable, to the point of you knowing what's going to happen long before you get there. It's pretty run of the mill horror here.
Overall, I couldn't recommend spending money on it. It was watchable and kept my interest, but if I had paid for it, I would've been pretty disappointed. It'll be on Shudder for free in no time, just wait for it til then.
