Even without considering the circumstances in which this work was done,
they would be excellent, but the context makes them even more
important. To see why look at the portrait about 55 secs into Arabella

When someone says that a movie is too violent, they usually mean that it made them feel uncomfortable because it portrayed violence too explicitly, and when I hear it, it makes angry, because they are asking for censorship. They want to deny themselves the only truly valuable depiction of violence on film: the reminder of exactly what it is that we do to each other every day, through wars, crimes, and stupid, preventable car accidents!
