Seductive in that it makes you feel sympathetic for two people who have an affair and care more about their own desires than they do about commitment. Francesca, in a letter written after her death, advises her to children to do whatever it takes to make themselves happy. For the son, it's a re-commitment to his own marriage. For the daughter, it's a separation from her husband. The movie was beautifully shot, although there really wasn't much time spent on the bridges themselves.
