This movie, to me, is not about how they meet, go through life or the open relationship. It is about that moment we always look for, the instant chemistry, which makes us euphoric and therefore happy. That bubble that everything is oke, everything is in line and I love somebody and that person loves me back in that moment.
The way this movie is shot, the high level of acting, it is as if you are watching your own life in some way. I think everybody can take moments from it and see what moments happen in their own life and how they react.
It is not intended as a movie to learn from, but just to hold a mirror up. It is not good or bad, just how we walk through life. To me, it is a good thing to keep realizing it.
If I had to pick one thing that stout out, I would say; that moment the bubble bursts. When you start to talk to each other and learn more about their way of thinking. At that point you are going to hear something you don't like and in an instant, your face changes and you need to deal with that emotion. That's when the euphoria stops and you try to get it back.
This review shows that this movie won't be for everybody, but watch past the first 10 minutes and get taken away by the emotions and reflect on yourself.
