A good movie that has big mistakes

Rating: 6/10 (15 January 2017)

The film is fine, keeps you stuck and keeps the tension all the time. It has very good moments and interesting turns.
It also has times when it seems like either there was no budget or they did not know how to do it. I'll comment on spoiler zone.
There are also times when it is predictable, but it is accomplished and you believe it and forgive it.
He deceives us at some point using the night camera, so let's see, because it suits him well, but I should have used photography in a different way. However the picture is pretty good, if it was not because I do not understand how that man has lights on at home.
It has an address that in some moments makes very interesting plans. It tells us and makes us go through fear showing everything and composing the plan. Takes the tension very well and keeps the excitement all the time. It overrides how predictable it is.
A film that fulfills its mission.
Spoiler:
What I do not like is how the time has come to save the girl who is going to be inseminated. I do not see anything, it does not fit the camera well. Also, since when the sperm is kept alive as maintained by the live?
I also do not like how he tricks us when he nails the kid the pruning shears and it turns out that they have been nailed to another.
