Read the log line and that's all you need. A student project at best.

Rating: 1/10 (18 August 2018)

This is, to me, a 3 star film. Why give 1 star? Because the ratings are wrong!
Since everyone at least starts watching movies knowing the basic premise, from the beginning it didn't generate "why? curiosity, A-ha" realization. We knew it all and... nothing really happens afterwards.
At the beginning, when the whole family leaves the youngest son behind. I go WTF. Is he not their son? This little boy lags way behind on the railroad (full of danger, where he can easily trip over). They never look back. When the noise erupts, the mother just stares for a long long moment. The whole thing is so unrealistic. So contrived. They needed a forced drama and shock, none of which I felt. From that moment on, it was flaw after flaw, hole after hole, cliche after cliche. I could predict every jump scare before it happened, including that open palm on the glass door. How many times do we have to see that?
Overall, it felt like a clumsy student project.
