The One I Love – Netflix DVD

I am a fan of Elizabeth Moss (Peggy from Mad Men) and Mark Duplass (of The League - TV's funniest show) so I was eager to see this movie, starring the pair of them.  It's a confusing one, and I would appreciate if you subscribers out there in Blogville would make comments here below the review to help elucidate what was going on and what the film was trying to convey. Ethan (Mark Duplass) and Sophie (Elizabeth Moss) were once a happy couple, but their marriage is now on the rocks.  They are in conjoint therapy, but it isn't helping much.  Their therapist (Ted Danson) suggests they spend a weekend on a beautiful estate retreat.  He has sent other struggling couples there, and they have returned "renewed." Ethan and Sophie decide to go.  After all, what have they got to lose?  The estate has a main house and a guest house.  Amazingly, when either Sophie or Ethan (each, alone) enter the guest house, they interact with a nearly identical - but slightly improved - version of their spouse.  The interactions between the actual Ethan and the alternate Sophie and the alternate Ethan and the actual Sophie then have a major impact on the actual Sophie and Ethan's relationship. Who are these doubles?  Are Ethan and Sophie having a mutual psychosis (folie a deux)?  Are they aliens?  Are Ethan and Sophie interacting with themselves from a different dimension?  If these alternates are real, how did they get there and how do they know everything about their lives? The acting is great, as Moss and Duplass act in subtle but different ways as themselves and their alternates. The film may possibly be about how our initial idealization of our spouse eventually dies from the day-to-day reality of life, but do our memories of the great moments and passion from the past interfere with our here-and-now appreciation of our spouse, thus spoiling the present? Please let me know your take on it.
