Not arguing at all that it should've been WW2 instead. My point in the previous post was that WW2 is given more emphasis than it should have already. The Lynda Carter show decided to be a period piece, and since then (because there's been so little live action Wonder Woman at all) some people have gotten the idea that Wonder Woman has to be in WW2. The original comics were published in the 1940s but the war isn't an essential piece of her mythology like it is to Captain America. I would'ved liked to see a Wonder Woman movie fully set in the present day.
I'll watch the movie and like it if it's well done. But to me it is a waste, if every supporting character from the WWI era is taken out of play from the sequels and confined to flashbacks. Getting one great Wonder Woman movie is a good thing. I just would've preferred several great Wonder Woman movies building up the same cast.
