Waste of time

Rating: 4/10 (23 May 2018)

This movie might be a good movie for deaf people. However, the story completely does not make sense.
1.How come the city is destroyed and they still have electricity?
2.How come those monsters who are afraid of high frequency and bullets can destroy the human society?
3. If the monsters' hearing are so sensitive, I believe they definitely can hear human breathe at a closed distance. But it seems they can't (at the end of movie)
4. Finally, I have to say the movie does not scare me at all. Wondering how does this movie get 8 out of 10!
