Concept okay. Acting good. Movie terrible

Rating: 1/10 (21 July 2018)

They hunt by sound and have no eyes and possibly nose. It doesn't take a genius to figure out that they'll have sensitive hearing.
I hate stupidity for the sake of moving on the plot. This was full of stupidity. The nail was the pinnacle of stupidity.
The movie would make more sense if they were say a couple of weeks after the attacks started not years.
