I watched this movie with my brother last night.. It was just ok but nothing more. . From the first 10 minutes my brother told me that the man is definitely the attacker and I told him I don't think because it would be very predictable. Of course it was extremely predictable....And it has no difference with many thrillers of similar plot. The fact that the man was all the characters can be considered as a twist, that you cannot predict it easily. But even this was not supported by the writers. I didn't like the scene that Ellen understood.. I wanted more passion. However I love Madelaine and her acting was great.
