I thought the previews looked like a movie with no plot and a lot of sex.
I can't stand Julia Roberts.
The movie never gets going and is only about constant partner swapping. You get every description of sex in every form. That pretty much sums up the movie. The plot was lost somewhere, but the drama is in trying to figure out which one is sleeping with who and it changes throughout the movie. The supsense was in thinking she was sleeping with her husband and cheating on her lover, but that she was really cheating on her husband and sleeping with her lover. That flips later. Gosh I hate to spoil the surprise for everyone.
At the end of the movie I looked at my husband and we both just said there is no way we waisted our time for this. As I left the theater a movie rater asked us to grade it from an A to an F. I said F and she said you are not alone in that rating! Someone else said D and someone said hey that's pretty high for this movie!
