Simplicity is more frightening than gore

Rating: 9/10 (15 June 2018)

Slashed throats . . . Why in hell are you going to open that door when 5 other buddies died in the past 5 minutes? . . . It's the formula we're used to seeing over and over . . .
Now the producers take under 15 million dollars, film in virtually 3 or four locations, have about 3-5 minutes of actual dialog for feature length film(!), all based on a simple concept, sound . . . what are some of you people whining about? Less is more in my book! I've seen all the usual techniques of horror and I'm sure I'll see even more in my day but the abject stress this film creates in almost every moment as a simple family tries survive is brilliant in its simplicity . . . in a virtual silence!
At first, the sign language thing was annoying, subtitling the signs. Until you find out why. And your most base human fear as a parent is the safety of your kids. One innocent mistake . . . just a simple playful sound . . . one of the most distressing scenes I've ever seen in a movie! That, folks, is the ultimate horror . . . and it doesn't get any easier for the next hour or so.
(To those who had a timing problem)
Yes, the time span indicated by "Day XXX" up into the 400's may cause some review bites. It basically would have worked just as well in a week time span by starting off "with child" instead of a year+ period. But that's just nitpicking. "Day 437" (or whatever) didn't even register as a problem until reading other reviews. You want logic? Watch a movie about Aristotle, Socrates or Plato. Ever heard of willful suspension of disbelief?" That's what movies are made for!
We're never told why or how this scenario occurred but who really cares? We know how the "Walking Dead" came about. Everyone's infected but they don't "turn" until death. Why? Who really cares? (No undead in this one, though! Just real human beings in a silent predicament.) Enjoy the tension for a couple of hours. Put yourself in their place. How would you handle it? Very quietly I hope . . .
Finally, Kleenex. No more elaboration. And if you don't think the last 30 seconds or so won't make you fist pump a couple of times . . . well, Freddie Kreuger is probably the ghoul of your dreams . . .
