The acting is fine, the scenery is pretty, but there's a huge pacing problem in this film. Sometimes stuff just "happens", out of the blue, barely explained. Other times just "nothing" happens at all. I understand the concept of "slow burn" movies, but this one was just slow.
And the "big reveal" / secret promised in this film? Please. If you've ever watched a film like this you'll have seen it coming 10 miles away.
