In Epidemic, one of his previous films, Lars von Trier noted that "a film must be like a stone in the shoe". Eleven years after Epidemic, Lars von Trier is famous, his budgets grew larger and so do the stones he puts in the spectators shoes. No, reality is never what you think it is. It stops moving when you expect it to rush, and than it rushes in a way that makes you dizzy. People that you considered to be serious collapse when it comes to testing their intentions in reality, and people that you never took a note of will prove to be the real heroes of life. At the same time Lars von Trier and his excellent actor ensemble try to explain why (non violent) social experiments always fail, in spite of what we learn at school and watch on TV. They fail for three main reasons. First, the intentions of the hardcore of every movement of this kind are different that the ones they declare on. Second, the few who take a social project seriously will remain outside the hardcore group in a lonely, non-influential position. And third: the external conditions for running an experiment of this kind are such, that it's impact is limited up front to zero, often without the acting persons realize it. A brilliant movie of a brilliant filmmaker, who revolutionized the cinema in the last generation. A must for every thinking person.
