What a big joke of a movie. She is a mutant.
1) She should not had survived the fall, her spine should had been broken, or paralyzed.
2)Shotgun is being used as a long range rifle.
3)the actress in the movie apparently has 100 times more blood than normal person.
4) She got a huge hole in her stomach which heals completely.
5) She was able to walk completely fine overnight, even though she got a big wound in the stomach.
6) One of the villain dies by being stabbed in the eye.
7) The main villain was already shot in the stomach by a shotgun and was able to stand up, walk and gave the heroine a good fight.
8) The corpse of Dimitri is found bloated in the water like it has been in there for weeks. There's no way a few hours submerged will deform a body like that.
9) When the villain pushes the heroine down the cliff, she gets impaled on a tree. To free herself from that situation, she sets fire to the tree. For the tree to get so dry for it to break under her weight, it would need quite some time. In that time, the flames and the heat would seriously hurt.
..And so many other errors...Unrealistic.
