Wow the characters are stupid

Rating: 5/10 (27 June 2018)

After seeing the trailer for this movie, I had high hopes for it but my hopes were immediately crushed due to the stupidity of the characters. They are so stupid it's beyond belief and I wonder how people are rating this movie so high.
89 days after an alien invasion, most of humanity has been wiped out by some creatures who are blind but have a keen sense of hearing. They hunt via noise and this is universally known. So when a family enter a small deserted town for supplies, you'd think they would all know to stay quiet. Nope, one of the children finds a toy rocket that lights up and makes noise and he wants to play with it. The father warns him about the noise (which he should know by now) and takes away the batteries only for the dumb kid to sneak some more batteries. Then stupid kid proceeds to put the batteries in the rocket and turn it on. Wow how dumb can you be? Yeah I know he's a kid but that's no excuse for hardheadedness. In fact, the father should have just taken the rocket away. Well the kid dies go figure.
Skip to 1 year later and the wife is pregnant. Ok. Did they even think about what would happen when the child is born? Nope. The lady decides to shack it up and get pregnant which in turn is so dumb as there's no way the baby will remain silent when it's born. *sigh* Supposedly the basement of their house is sound proof but that doesn't include the stairs cause the wife goes into labor and while going down into the basement, steps on a nail (How the heck is a nail sticking out for her to step on without anyone noticing) and drops a picture frame which alerts one of the monsters to the house. Luckily they are able to hide the newborn in a box without the monsters finding out where they are at.
It gets even sillier with the basement flooding somehow, the kids falling into a silo which attracts another monster and the father dying because his kids just won't shut the hell up. Wow.
It ends with the children finding out that high frequency noise can disable the monsters temporarily allowing the mother to shoot a loud shotgun killing one of the creatures. Of course, this just invites more to the house. The mother grins like she's a winner and get ready to fight the two new monsters not even thinking that she's about to run out of bullets and each time she shoots, more just shows up. Wow oh wow.
