Among the dumbest movies I have ever had the misfortune to waste my time watching. The acting, directing, filming are all fine but, even if you are devoid of any understanding of how sound works, the movie itself provides more than enough information to contradict its own premise and cause its own downfall.
Had the movie been about an isolated incident where a family is somehow trapped by these monsters and have to figure out how to survive it would have a relatively enjoyable film. As it stand though, anyone exercising the most rudimentary of critical thinking skills will find the premise that for more than a year the entire world has been at the mercy of creatures who are easily fooled, easily distracted, have an easily exploitable weakness, and are relatively easy to kill too unbelievable to enjoy.
