well, have you seen dogville? grace is much smarter than selma and bess.
Had you seen all of his films, you would know that lars' style isn't all the same for sure. You would know that his first trilogy was,visually, very different than his later work and had men for lead characters .had you seen medea, you would know that he has portrayed women as sadistic evil bitches. One thing that is constant through all his films are great dramatic endings that make me numb.
I don't understand what you mean by stupid things and bad results...one might say that they sacrifice themselves for the person they love and the result is that they save them.
you shouldn't be bothered by that
