Right off I knew that there was conflict between the woman and her man. She was distant and the man was trying to energize the situation somehow. The reason for the conflict is revealed a few minutes into the movie and ties in later especially at the end. The scenery was not spectacular although I live near the mountains so I might be spoiled. However, the setting was just right for this kind of movie It did not need to be spectacular; it needed to fit the plot and. I believe it did. The female lead is not a likable person and this works well with the plot as things change. There is a French or Swiss movie I saw several years ago and I believe writer of The Frozen has seen this movie. They are similar but sufficiently different. I liked them both which proved to me that variations on a theme can be successful. Don't expect to be horrified or bloody freaked out. It won't happen. Go with the flow and you might find yourself satisfied at the conclusion. The acting worked for me. Obviously, others do not agree with my assessment but hey, that's life.
I am partially deaf so I watch movies with the captioning. Therefore, my experience is likely different from those who can hear well. I miss the vocal nuances and pick up on other physical queues.
