Slow paced and full of holes

Rating: 3/10 (23 April 2018)

First of all, I rarely review movies, but I really have to speak out this time.
The 3 stars I gave were for exactly three memorable scenes (deaths included, of course). Aside from those, things went too slow. Hence, nervous as you may, you also have to try either to not fall asleep or to make noticeable sounds, which is quite frustrating.
I gotta mentions some negatives, which my mind took too seriously I got no room left for imagination or anticipation.
1. I have no emotions whatsoever towards the characters. They were neither likeable nor annoying, just blandly ordinary people, so I didn't really care what would happen to them.
2. The worst possible outcome of the creature's attacks is a fast and easy death. Not so new or unexpected, eh? Furthermore, there wasn't much blood or gore at all (well this can be a positive point - depends on your preference).
3. Where is everybody else? Dead, you can argue, but what about the supplies for this family? How do they get the electricity and water running, and a huge amount of candles burning all this time? Same goes for food and goods, they have lived more than a year on their own. They cannot drive either, to prevent causing noise. Eventually they would run out of supplies, despite their being "near" marts or so.
4. This one big scene, when the wife caused noise, the first entry of the creatures didn't make any sound. Same with some other times they moved in and out. Did they gracefully open the unlocked door and walked in?
5. In the rescue scene, why did the dad leave their home with not much in hand? Why not a gun? He knew too well he gotta protect his children, yet he ended up using an useless crowbar (iirc), and ended up failing.
6. The mommy's staircase incident. Why didn't the kids have that too? Why didn't their mom warn them about it?
___
And the list goes on. But you gotta see it for yourself.
Nevertheless, the acting was brilliant, and I love the characters' house/ clothing/ lifestyle.
I don't mind the unknown creatures and the abrupt ending. I just wish everything were handled more rationally.
