I am giving this a 4 because of the ending. I don't give spoilers, but I just didn't like the ending! I think the overall plot had a great potential, and yes, it has a plot where other people said there wasn't. If I would have realized that the closed caption (subtitles) worked for the foreign languages spoke in this movie existed when you chose that, it probably would have earned 5 stars. Some people say this it's slow moving, and yes, it definitely is, however, I feel it set the picture for the setting. The hired maid/housekeeper seems quite normal, and so do the hiring couple. The description of the movie; however, it not accurate, nor is it a thriller or a horror film. My advise - Be ready for a slow moving movie and turn on the CC!
