The film I'd fight over
Why is it, that whenever a film tells a story about life, without explaining it, people become so confused? Think of every relationship, even minor friendships, even with a coworker, and how they start. We all make choices and decisions on what to convey, either with words or gestures and what we hide. In terms of relationships, we open up and let down our guard, allowing others in or in many cases, hiding those secrets away that might give away too much.
The entire film is the balance between needing companionship and solitude. The two leads have taken entirely different paths and don't want to walk down them again, both literally and figuratively. It's the respect for one another's privacy and one another's past that allows for the relationship to blossom. They each admire the other one for their differences, but find common ground....and for those not liking the ending, it's the same as the beginning, you just didn't pay attention.
