I think that says it all.
You'll understand if you watch this movie.
It's a monster movie. Bunch of weird monsters.
The opening family is really weird. All through the movie, you'll be thinking that they were really robots, or something to explain their weirdness and stiffness.
But it never happens.
In its defense, I'll say that it certainly looks like some very important information was CUT. Maybe more was filmed, maybe more was scheduled to be filmed. It wouldn't take much to add for some coherent story line or character line.
Mostly, the military angle looked like something was cut. The two surviving soldiers who join the isolated group have weapons that never work. That is possibly what is missing from the story. Were they given decrepit weapons on purpose by humans, or was there a supernatural reason? Nothing is indicated either way. Was there a scene cut from the movie to explain this? The woman playing the military leader gets top billing, even though the family is center stage, so I'm inclined to believe there was initially more to the script.
Until that is added on to the movie, I have to grade it on its merits as is. So, here goes:
We learn many lessons. The people in the military are given weapons that don't function. And eventually the ones who survive learn to just toss those weapons away.
We learn that if a beast is about to eat you, to stand and talk and don't run away or drive away for a good 15 seconds. This is to ensure that the slower beasts don't get their meal, and you get to feed faster beasts who will breed faster beasts.
Many such lessons.
The motivations for the characters? Well, some are motivated, and some are just kind of "lets just have this character do this thing here". Notably a stereotypical religious nut and the family from the beginning.
I'll be lax on the rating, because I do believe the panic in panic situations. That's the only thing going for this movie. People not acting calm and cool when huge dangerous beasts are maiming and tearing their bodies apart.
But it total?
I think it can all be summed up with:
Huh?
