I enjoyed this film. It is different. I can't recall seeing another movie that is quite like it.
Elizabeth is a newlywed who is honeymooning with her much older billionaire husband at his private mountain property. The only other people present are a female and blind male who are servants. The home is rather large and Elizabeth is free to enjoy all areas of the property with the only exception being a room that her husband, whom we learn to be a intelligent man of science, has specifically denied her access to. Elizabeth, who seems to come off as a bit ditsy, has a curious nature chooses to explore the room after her husband goes out of town on business. It is at this point she learns more than she bargained for and her life takes a turn for the worse.
That is about all I can say about the plot without adding spoilers but I didn't see what was coming and I love that about this film. You are introduced to several different plot twists that pull you in different directions. I've seen that a few people weren't impressed by our lead actress and felt that her acting was off. I didn't feel that way. I felt that her acting was very much in line with her character and what may have initially seemed like bad acting is revealed to be a part of her character.
I liked it and felt as though it was a good watch.
