Intimacy means allowing someone else into the most hidden parts of ourselves. When someone is close to us they see behind the walls we construct - personal, financial, social, protective. Knowing what others don't know is a form of special access. It makes can bring us closer together, but it also makes them powerful, We trust that the power we have given will not be used against us. Gone Girl is a story about what happens when that trust is abused. For the story to work Amy and Nick need to know most everything about each other - yet still be capable of surprising their partner. In each case they use the power of their intimacy against the other. In each case they have kept something from their partner, something important.
Intimacy is also about commitment. Commitment runs throughout every page of this story. Who is committed to whom. Who is committed to what. What happens when commitment falters, or becomes twisted. The story is especially powerful when we get to see both two sides to Amy' commitment.
Intimacy and generous commitment are among foundations of solid, meaningful, positive relationships. But when they become warped relationships verge into dark places. Finally Nick and Amy's relationship is about competition. Who, each by their own standards, will emerge as the winner?
