These people are so stupid. Based on a random meeting, Anna and Domenico strike up a hot and heavy illicit affair. So they're attracted to each other; they gave themselves plenty of opportunities to let reason take hold, but still kept meeting. Anna has a very nice, if a bit goofy, live-in boyfriend. Domenico has a faithful, attractive wife who stays home caring for their young children. Needless to say, Anna and Domenico are simply selfish, creating an unsustainable, costly, and irresponsible relationship, if you can even call it that. Basic story, they meet, they decide to have sex, they know they should quit meeting but can't, wonder, "Why couldn't we have met sooner?", then they have to figure out whether to stay together. Sorry not to have anything to say about the quality of this movie as a movie, I just couldn't stand it.
Bottom line, no stars.
