On a storytelling level, I’m not sure Wonder Woman 1984 could have been set at a worse possible time.
Patty Jenkins clearly had some ideas she wanted Wonder Woman 1984 to express about the 1980s and, by extension, about the 2020s.
The setting of the new Wonder Woman sequel is so important that Warner Bros. and director Patty Jenkins made it the title of the film; it’s not Wonder Woman 2, it’s Wonder Woman 1984.
And it can’t fill in Diana’s backstory the way a traditional prequel would, because the original Wonder Woman already did that.
