This is a love story about two broken people (Michael stated that all people are broken)trying to find repair (salvation, redemption, purpose, etc.) through love. However, the damages that Michael and Sophie bring into the relationship makes it difficult for them to develop a relationship.
Michael is a masochist and Sophie is a dominatrix by profession who caters to masochistic men. You would thus think they were soul mates. However, Sophie only role plays her sadistic posture in her work and is not truly a dominatrix personally. Michael is a failure with many redeeming qualities and his masochism mollifies his failures and subsequent depression. Both enter the relationship hiding something from each other, and this serves as an invisible barrier to their love.
For the first time in her life, Sophie overcomes her anxiety over intimate love and finds herself falling in love, following Michael's lead in his dependent need for her.
However, Michael reveals himself as a pathetic failure who deceived her and she leaves him with disastrous consequences.
The movie's ending is disappointing since the potential for developing a love relationship could have been actualized with time and proper honest communication.
The movie is extremely well done in all aspects except the ending. The ending could have easily been revised in different ways to make a fulfilling story.
Manuel Bonnet as Michael and Lizzie Brocheré as Sophie were both superb. For me, Brocheré's performance ranks with that of Giulietta Massina in "La Strada" as one of the best female performances.
