Harsher in Hindsight: It was intended as a documentary film to show the Germans how great the Nazi regime was and how The Future Will Be Better. However, since the end of World War II it's difficult to watch this movie without keeping in mind what horrors all this would lead to in the end.
Ho Yay: Not just the shirtless frolicking stormtroopers. Check out the glow in Rudolf Hess' eyes when he introduces Hitler's last speech.
The short segment with the SS Leibstandarten Adolf Hitler guys holding onto each other's belts in a show of camaraderie.
And just look at the young men's eyes when their Führer speaks.
One-Scene Wonder: The incredibly enthusiastic and wide-eyed speaker of the Labor Service.
Seinfeld Is Unfunny: Unfunny isn't quite the right word, but this was quite an innovative movie when it was made, and has inspired many a scene (and originated some now fairly standard techniques) since then — with the result that very little in the movie seems original after some seven decades of people copying things from it.
Sequel Displacement: Riefenstahl made this as a follow-up to Victory of Faith, which chronicled the 1933 Party rally. That movie however was suppressed by the German government after the Night of the Long Knives, for prominently featuring Ernst Rohm and the SA. Victory remains comparatively obscure, and considered inferior by most who have seen it.
