I watch mostly Foreign Films, Documentaries,and or Cannes types of Films and I have to say I really liked this film. It has a little of everything. Love, humor, sex, realism. It is just a "nice" film without being boring at all. Most French Films I have watched end and then one has to come up with their own ending. This one does leave some mystery as to exactly what they did or did not do but you find yourself ok with the ending instead of being frustrated (like many French Films can leave you feeling....think "Irreversible", for one).
I decided to edit my review (7/14/2014) sorry to any others who read it before. I felt I gave to much away in the past review..
An Affair of Love is for people who like a lot of dialogue and who are into Foreign Films with depth so it is not for everyone. Another great "nice" love movie with an outstanding director and cast is In the Mood for Love, by Wong Kar-Wai.(But again is a "nice" movie, drama free so not for everyone)
