Blake Petit’s review published on Letterboxd :
2018 Superhero Rewatch: In which I return to superhero movies I've seen before to see how time has treated them.
Crooks in a rocket-powered "Bullet Car" car go on a crime spree, destroying police headquarters in their quest and demanding the city treasury or they'll destroy everything else. In these early cartoons, there weren't really "supervillains" in the modern sense. The occasional mad scientist or monster, but not really the evil equivalent of the superhero. The rocket car is one of the closest things we got to that trope in these days. I love these shorts.
