Amateurish. There are Nazi films that are more racist and anti-Semitic than Mel Gibson’s (or maybe even Leni Riefenstal’s).
Wondering also 1) if Fu Manchu was supposed to be one of China’s despotic Manchu overlords, and 2) if Fu had been Japanese would there have been as much outrage, given what the Japs were doing in the 30s.
