A very young woman marries an older doctor. In their honeymoon he shows his impressive house and explains that everything belongs to her but there is one room she should never get into. As it obvious she did to and things get very ugly.
Explaining more will ruin the many unpredictable surprises after that event. The movie becomes more interesting and engaging even when its pace is it sometimes a bit slow.
The cast is perfect with the calm tone of the movie. Abbey Lee is surprisingly good in a character that needs to generate empathy and sympathy in order for the movie to work.
Ciarán Hinds and Matthew Beard are intriguing and mix of good and diabolic as they can be without much effort. The underrated Carla Gugino perfectly handles a mysterious character whose motivations are unclear until the very end.
The only major critics could be; the pace that is sometimes a bit slow and those looking for pure horror will be disappointed; this is mix of science fiction and horror; but overall there are many interesting things to think about that will stay with you after the movie ends.
In brief; far from shallow a movie that deserves to be seen
