^^^If the entire trilogy is Triumph of the Will, maybe it's a good thing to miss the point?
Beyond the obvious joke, especially if the movies' overall theme is the will, skipping over physical reality falsifies the theme. Physical reality is an inescapable constraint. Wishing it away with FX and appeals to genre conventions means loading the dice, instead of honestly confronting the issues involved. Which do include physical reality for one.
Even if you try to reduce the will in these movies to a matter of being willing to believe in myths or to enact those myths, the assumption that myth binds society or polity is a gross misreading of the human world. On that level it's all too silly for words.
