Not perfect, but we'll worth a watch/listen

Rating: 9/10 (6 October 2019)

Let's begin spoiler-free: this movie is extremely well made. The performances are outstanding (almost entirely silent), the tension ebbs and flows beautifully (though my wife and I did inappropriately laugh out loud during the Titanic scene), the creatures are terrifying, and astute viewers are adequately informed. To explain some of the "plot holes", I'll go into spoiler territory, but first I'm going to come right out and say it: the movie doesn't have to tell us a darn thing about the monster. Some movies do, some don't. Often, the better/scarier/tenser ones are those that don't. Go watch The Birds sometime...it's a gold standard, and ends very similarly to A Quiet Place
**SPOILERS**
In no particular order...
~ You actually need to pay attention to the movie, including reading. The next few points can be attributed to either ASL subtitles or written media that our attention is drawn to
~ The creatures are armored, meaning bullets don't affect them...unless of course their faces are open
~ The newborn is multiple weeks premature (and no, it doesn't look it...even regular "newborns" are played by infants)
~ The father had been working on a way to amplify high frequencies. This is the last of the written stuff I'll point out
~ People farmed before combustion engines
~ Building a house (or any substantial shelter) is loud, even in places not exactly where the shelter will stand
~ Extracting a nail is loud
~ Doors are loud
~ Shoes are loud (no matter how hard you try)
~ Children are children
~ Teenagers are teenagers
~ People are people
~ Pull-out isn't reliable, and all forms of manual birth control have expirations for a reason
~ Mistakes made by characters are not plot holes. Bad decisions made by characters are not plot holes
~ Many of "the rules" are established thoroughly and gradually (which is *great*). At one point I turned to my wife and said "I wonder if they attack animals besides humans", prompted by an event in the movie, and the answer came within minutes. It *sets you up* to be ready for a "rule", then delivers. And just like the backstory, you don't need to know all of the rules (as long as they're not wildly inconsistent)
No, it's not perfect. I'm not giving it a 10, though I'm tempted just to offset
