His last four movies ( "Breaking the Waves," "The Idiots," "Dancer in the Dark" and now "Dogville") have all dealt largely with the psychological (and sometimes physical) torture of vulnerable female protagonists.
Experience of his recent work - Breaking the Waves, The Idiots, Dancer in the Dark - suggests he has an instinct for getting up people's noses but remains clueless (or perhaps careless) about pleasing the eye or the ear.
No discussion of Lars von Trier's Breaking the Waves, Dancer in the Dark, or Dogville--the three of which we'll collectively call the "Martyr Trilogy" (von Trier has his own, ludicrous umbrella term for Breaking the Waves, Dancer in the Dark, and the intervening The Idiots--the "Good-Heart Trilogy"--and insists that Dogville is part one of a proposed "American" trilogy (Manderlay, the unlikely sequel, will deal with "slavery"))--is complete without citing Dreyer's 1928 silent The Passion of Joan of Arc as a primary influence.
The proof was in the plodding: Although there have been a few genuinely absorbing and entertaining Dogme movies ("The Celebration" and "Italian for Beginners" leap to mind), most of them, including von Trier's own tiresome exercise "The Idiots," have been little more than pretentious, self-conscious film-school essays that have received publicity not because of any inherent interest or artistry but because their directors have usually accompanied their releases with tortured mea culpas about the vows that they broke, such as pulling back a curtain to increase a room's light.
