I had read the book before I saw the movie, and there is a very important fact in the story from the book that never made it to the movie. Had this point been made the audience would have known the reasons behind the actions and then the movie would have made sense, therefore, maybe the movie would have been rated higher. Otherwise, the movie was okay and mostly entertaining and an easy movie to watch. It does not require a lot of thinking, well, for those of us who read the book and know why the 3 are doing what they are doing. Each actress plays her usual character self, seen often enough for each, and the the chemistry between the 3 actresses worked.
