I haven't seen the previous movie, which this one follows. But I don't think that it matters that much. This movie with a heavy burden is really hard to swallow. The German actor who plays along William Dafoe said so himself. At the Berlinale screening he came up after the movie and stated (more or less, this is not an exact quote): "It is my first time watching this movie, too. I have to admit it's pretty heavy and hard to watch!"
Which made me admire the actor even more (he also played "Hitler" in the movie "Downfall"). And considering the ending of this movie is really lyrical and aspirational, it's almost a shame, that I really had to fight myself during other parts of the movie. It's an odd movie, which definitely will strike a nerve with the viewer. The only question is, will it be an enjoyable enough experience or not? I can't answer that for you, but it's slow pace and a storyline that is anything but linear, will confuse and appall more people than it will attract
