I don’t think there’s any entry in the Marvel Cinematic Universe as divisive as Iron Man 3. Shane Black’s 2013 comic book techno-thriller was a hit both with critics and at the box office, and also a crucial stage in the personal arc of Robert Downey jr.’s Tony Stark. And yet, some fans still hated it. And a lot of that enmity was down to how Marvel handled the Mandarin.
Created by Stan Lee and Don Heck in 1964, The Mandarin was one of Iron Man’s arch-nemeses in the comics. A descendant of Gengis Khan, the Mandarin inherited his progenitor’s lust for domination, which he tried to exact using his genius intellect as well as ten “magical” rings – actually repurposed extraterrestrial technology salvaged from a crashed spaceship. He was also a walking collection of terrible Asian stereotypes and caricatures. This was clearly a problem.
