You've seen this sort of picture  People get drunk and drag skeletons out of closets, and the tension between the formal dinner party rituals and the truths that simmer beneath the surface give way to a Walpurgisnacht . The anti-patriarchal content is fairly routine, but you should see the movie anyway because the director, Thomas Vinterberg, is a great, hypersensitive filmmaker whose edgy, grainy, caught-on-the-fly camerawork seems to make the very celluloid shiver with rage.
Thomas Vinterberg is an outstanding film director and producer.
