Apart from the fact that the scenes are just too bloody, the ending is incredibly stupid. The fact that they could have escaped the mountains when they were on the 'racist's brother' bike on the way to the cabin is considerably messed up. That same bike that worked perfectly to the cabin at first now refused to 'start' when they were just about leaving. Also, when they entered the cabin and Nadja asked Einar to call police to come to their aid, even after Nadja found out he was calling another person, she still stood there like a dummy and Einar(with a scared look) threatens them to move back and in fear, they enter a room with open windows for escape - but they were successfully able to take down someone that has a gun with just a stone.
And how on Earth does a kid show up on a highway without looking left or right but straight up in the sky at a drone even after the car would have made some speed noise. The father
who was watching through the drone from the cabin should have spotted the car afar but didn't think of redirecting the drone back into the woods so the boy can follow up and leave the highway. Instead, he watched his son being hit by a car and then starts runnung to him to 'mourn'. At the ending, Nadja seals faith with David and he tells her to go stating that he wouldn't make it out alive if they continued lime this. After leaving, she stupidly comes back and this time, has a gun that is loaded but waits and watches Tomas put down his gun and start his whole speech knowing fully well that he is a wide enemy and can pull up a smart game if she doesn't shoot him.
Finally, here comes the all-mighty invisible wife of Tomas coming up only in the last scene of the play with a gun(which is of no use considering the fact that Tomas told her to come and witness her child's killers as he(Tomas) tortures Nadja and David - so why carry a gun?) and shoots Nadja unexpectedly.
For me, the last scene spoils it all.
