SUSPENSEFUL, A MIX OF "10 CLOVER-FIELD LANE" AND "TREMORS". SPOILER ALERT.

Rating: 8/10 (7 April 2018)

I really liked this film. It was suspenseful and had an air of fear throughout. The element of silence brought attention to every sound that was made.
I also truly think this film is daring. In the trailer it left you open to whether or not he saved his child from the monster.
There are some lapses in logic. For instance if you could talk at the waterfall why not move there? Why not move the pregnant wife to the waterfall where she could scream and be safe--that would a problem but obviously she broke water ahead of the due date, so their plans were put to the test.
I loved the acting, a very interesting concept as 90% of the acting relies on pantomime and sign language which helps you notice the actors faces. The children actors were very effective and the relationships between the characters were touching though a little cliche, but a good kind of cliche.
I have one major compliment and one major beef with the film. They both concern the monsters.
I compliment the mystery of the creatures in this film, they do not tell us where they came from. The most we get is "Angels of Death." This mysterious element of not telling the audience if these creatures are aliens, demons, or experiments leads the audience to the unknown. The unknown is perhaps one of the most effective elements in horror. This could even lead to the possibility of explaining these creatures as merely coming into existence suddenly with no explanation. The characters, like the audience do not know what these things are. I love this, perhaps these monsters should originate from out of the blue, merely appearing and causing the near extinction of the human race.
My beef with the monsters is that we got to see them up close and personal. My first sight of the monster as a blur on the screen was very effective, but as they came closer I realized they were more generic and something you could easily find online, and very similar to the "Venom" character of spider-man in the facial region, with elements of other monsters such as the Xenomorph from the "Alien" films. What would have helped the monsters would have been to, at the very least, keep them fast blurs and at the most keep them just off screen, unless there was a concept that would have worked better. (The "Venom/Alien" look relies on the uncanny valley effect of humanoid horror.) By not showing your monster you can increase the element of the unknown.
The monsters could also tunnel through metal silos in one scene but then have issues cutting through a truck in the next....definitely a plot convenience, though in this film you'll find the family can barely catch a break.
The world was very post apocalyptic, and for this film that worked. They used the old "Tremors" gimmick of not making noise or the monster gets ya! And the basement and fear reminded me of "10 Clover-field Lane", another film that used elements of the unknown while also using psychological horror and human tension.
Cinematography-no regrets very clear, very nice.
Framing/Composition - very communicative and very effective use of show, don't tell, most notably when they show you that the wife is pregnant.
Sound/Foley - Very, very effective in a film that required a usage of soft noises where the characters were attempting to achieve silence.
There was several uses of Set Up and Pay Off, where characters and ideas were introduced to be utilized later in the film.
I wouldn't have lasted a day out there myself.
