Stupidly Good!
Damn, the difference between a good director at the height of his powers and everyone else is just insane, but...
Why on Earth did the studio greenlight this AFTER SCHOOL SPECIAL? Was someone having a laugh? Was the US government this determined to push social engineering propaganda as the war ended?
Think of what we might have had if Billy Wilder had been tasked to write/direct an INTERESTING story. Yeah, we can marvel at the quality of this movie, but it would have been funnier (reefer madness style) if a really bad director had made it, and thus allowed a rare talent to focus on a film that mattered.
