The real relationships between the characters, past or present?
I think I liked this film, but I am still not sure what the parallel lives thing was about. Were we seeing flashbacks to the 30-year-old woman's youth? Was the younger couple really there in the present story, but in some other form, not quite real? What was fantasy, or what was mis-remembered past?
If anybody has a handle on the movie's plot, the surface tale and sub-text, please tell me!
