This film was really a big, unexpected surprise. First of all, the wife said it was a 'British drama' and it turned out to be an American comedy. Second, the scenario is extremely daring, especially the opening scene (can't tell you what it is about... that would be a huge spoiler). The film then unfolds as a cheeky romantic comedy of sorts, except that it does raise quite a few questions about love, family life, and oneself vs the others (not l'enfer c'est les autres à la Sartre, but almost!).
Highly recommended (but definitely not for kids or the faint-hearted).
PS - Kudos for Melinda Page Hamilton... Hers was quite a difficult role to play!
