Brilliant, the tension builds up very well until it comes to action. Interesting and charismatic characters, you can't guess what's going to happen, Marla is pure evil. However, i can't agree with the fact that pure "determination" makes you survive to anything. I could really feel that at some point, realism is lacking, i mean it's following such a strict script, logic doesn't follow, just like Roman's behaviour to Marla or his mother. The very end is... a nonsense
