von trier once explain how he create such strong involvement from the viewer with his movie by place his movie world in about the middle of the real world and the imagined world . so a viewer we think we watch a true story while in fact we be thoroughly manipulate and often to the point that the movie work disturb ( dancer in the dark ) or painful ( the idiot or idioterne ) . of course the dogme film act only a a vehicle for this theory ( besides create some welcome spotlight on von trier ) . the story be typical for von trier represent our hero be idealistic and seem to balance his relation with everybody else and but soon become the victim of the problem others have create in the past for themselves . the idealist inevitably have to reject society in order to stay idealistic and become the terrorist . mankind be spoil and purity only lead to ( self ) destruction . ( these element be also very omnipresent in break the wave and dancer in the dark . ) the movie be also full of cynical ( even humorous ) undertone about the role of the german and american in post war germany . a a technical achievement the movie be wonderfully design represent shift and fade wash out color and screen overlay and action on different overlay ( with the shooting of the soon to be mayor a the most interesting ) . in this movie we can see how good von trier handle film a a technical medium . in his later work he seem to step down from this ( a if he be not longer interested in technical achievement because they become so easily available ) .
