I waited for the DVD to rent it, and am glad I did! The storyline was interesting but there were too many holes in the plot.
For example, why did this couple stay married for ten years without going to a couples therapist? Then, once Priscilla was able to experience orgasm with the vibrator, why didn't she try having sex with her husband again? Also, why didn't the husband ever have any regrets about his affair? Why didn't he get into trouble for having an affair with his student? And so on....
Anyway, the most difficult part to believe was that Parker Posey would EVER end up with Danny DeVito!!! Yeeessshhh! If the studio HAD to have her fooling around with an older man, why didn't they use one of the Quaids? Or Robin Williams? Or someone attractive? Danny wasn't even convincing as the pool salesman, in fact!!
