I watched this movie yesterday and I really liked it. I don't think it was made to be realistic, instead I saw it like a caricature of us, humans. We crave for safety and order, but we also crave for love and acceptance. These things are often at odds, because each of us is a well of creativity and unpredictability. When we try to have a very orderly, predictable life we often need to lie, to others and ourselves.
I don't think this movie is a about sexual chemistry and things like that. I think it's about love and acceptance. It's about true stability, not about being able to predict how the future will be like, but the ability to know that some people will not abandon us, even when we make terrible mistakes. Instead, they'll try to understand. That's true security. I think this movie is about the most important topic of all: to be true to oneself. And it treats the subject in a light manner. Not a perfect movie, but I liked watching it!
