Contradicting to the general rating, I actually quite enjoyed it because of the below reasons:
1. Got a sneak peak of Polish acting (I have not seen many Polish films)
2. Enjoyed the modernistic approach to better suit new audience
3. Was a bit different than the usual : a hunk dude and the girl fall in love and end up surviving
4. I found the kids' acting much better than a lot of other movies
5. A few jump scares
What I would have liked to see more was what happened to the other kids? Did they go through this monster chase as well?
Sure, we have a lot of better slasher movies but this was nice as well.
