We watched The One I Love last night. It is the story of a troubled couple who go away for a weekend to repair their marriage. The film shows each of the partners vacillating between their open accepting self and their defended suspicious self, and makes the destructive nature of the latter very clear.
The movie has a creative plot device that makes it more than just the anatomy of a relationship, and I can thoroughly recommend it. If you’re a Mad Men fan, it has the added pleasure of seeing Elisabeth Moss (Peggy) in a different role.
