I am old fashion enough to expect mysteries resolved by the end of a movie, so I was initially disappointed when it ended otherwise. Yet it captured my fascination at every moment, and I believed I was watching events happening to real people, in the setting my father described when relating his growing up in Germany as a child before World War I. The black and white was especially effective in conveying the mood. Repeatedly horrified by what seemingly good people can do to one another, culminating in the start of World War I, I concluded that this was the message of the film itself: We should all think harder about why there is so much evil in the world, and what part do we play in perpetuating it, or preventing it. Superbly crafted.
