The number of spam-bots (or racist/political door knobs) posting the exact same one-star, negative review is annoying. It also skews the reviews, which is exactly the intent of these idiots.
As far as the movie goes though, I felt it was thought-provoking, timely, and well executed. I've never been a Julia Roberts fan, but her character was quasi unlikable, which was appropriate. All in all, my wife and I enjoyed the story and the ending, which some people complained about, seemed open fine to us.
