Don’t Breathe is an interesting trailer that comes off as the anti-Hush, if you will.
Hush, currently on Netflix, revolves a woman who–if I recall–loses her voice to a bout of meningitis at some point in her past.
She ends up terrorized by a killer and she’s unable to call for help because the aforementioned infection robbed her of her voice.
The point being, Don’t Breathe takes a similar approach, though makes the bad guy–if the trailer is any indicator–blind.
What’s pretty clever is that in one instance the blind man has his prey in a dark room, putting everyone on even ground, which I am not sure that I buy because being unable to see doesn’t mean that your remaining senses are any sharper; so a blind person in a unfamiliar dark room would be no better off than a sighted person in a room too dark to see in.
Though if the blind person were in a familiar location…the equation changes demonstrably.
