A plot-hole fest yet entertaining

Rating: 6/10 (5 March 2017)

There is no way for me to give the movie a lower rating than 6. The acting and directing definitely make it a decently entertaining experience. That is if you're willing to switch of your brain for the duration of the movie.
I really don't mind a film in which none of the protagonists is really likable. Usually actually quite enjoy that style of storytelling, but edgy characters just don't help if too much stuff just doesn't add up.
I am not going to recap or summarize the movie. IMDb and many other reviews did that before.
Either you are still interested in watching the movie and then, again, as long as you're just up for some suspense without much thought, by all means go for it. You won't feel like you lost 90min of your life.
But be aware, it is a true plot-hole fest. If you mind that this is not for you.
Here is were I give my SPOILER WARNING! What follows are all the plot holes I could spot, so don't continue reading if you want to discover them yourself!
1. Why is it presumed he will keep his reconciliation money in cash at home?
2. While entering the home the three kids cause the dog to bark, rattle locks, smash glass... Our blind friend remains in slumber land, no problem.
3. Somehow the blind guy is immune to gas.
4. Once awake the blind vet's perception abilities are definitely heightened but quite selectively so. He can hear them breath. He hears a faint creaking of the floor. He smells their shoes from a two meter distance. Yet he is unable to smell them or feel their body heat when they are passing him bleeding and sweating in not even an arms length distance.
5. Why does he have an alarm system linked to the police when he has a kidnapped impregnated girl down in his basement?
6. This one is not a plot-hole but rather an uncalled for moral lesson by the writer. When the girl is about to take the place of the priorly kidnapped girl and starts praying he tells her 'there is no god, once a man realizes that he can do anything'. Yeah, right. Cause faith totally kept those kids from breaking into a blind man's home and also in general keeps people from say... raping kids, beheading people... While people without faith can't possibly have morality. F off.
7. Anyway, next plot-hole. When trying to impregnate here he cuts her jeans with huge scissors. We know he's successful cause he is about to proceed with inseminating her. However once her friend comes to the rescue her jeans miraculously recover completely which we can see perfectly in the ass shot during the dog-car scene. Man, I want a pair of those self repairing jeans.
8. Also, to keep sperm in a fridge is not that simple and you surely cannot warm it up on a gas stove. Destroys the protein. Renders the sperm useless. Complete BS.
9. I also really would like to know how the police just shrugged off his obvious sex kink kidnapping corner and home made sperm bank inside his basement. As well as the insane amounts of blood everywhere at least one DNA of which doesn't match with any of the dead burglars...
10. Also interesting when the girl who killed his daughter vanished the police seemingly didn't look into him at all.
So yeah, it just didn't add up at quite too many spots. Not blown away. Still the acting and directing were not bad, so it wasn't a complete waste of time.
