Number 1 > The STORY may be simple (some may say predictable at some points) but it is FULL OF REALISM. It may remind you a nightmare that you once experienced and you would never want that to be true.
Number 2 > Performances are very convincing. It makes you feel that you are in the two antiheroes' shoes. And believe me it is quite uncomfortable since their positions are EXTREMELY UNPLEASANT.
Number 3 > CINEMATOGRAPHY & MOOD is perfect; full of Scottish rural scenery.
Conclusion:
I would suggest not to watch trailers or various movie scenes and not to read anything about how the story unfolds. If you like intense thriller as well as Scottish village and woods scenery, just go for it.
