Too noisy

Interesting concept but loopholed to shit. Alien monsters have inhabited the Earth. They are blind but have a super-hearing, so in order to survive people have to be super-quiet. Turns out though that they are as easy to kill as anything on this planet. Don't know how many people gathered up to write the script, but they are imbeciles. Ridiculously laughable mistakes, forced plot twists and deductive reasonings.
