Personally I had to google to understand this film. I'm sure if I had the patience to look further into the logic of mother , then I would maybe understand more. However, after a long day at work I decide to watch a good thriller/horror to chill out have a glass of wine & dinner....... this is not the movie for that. Confused me from beginning to end. Maybe I'm just slightly dense, but I just don't get how the everyday person would ever put two & two together and understand the story line. No offense to the film, just not an easy watch.
