Regarding the "doesn't have enough girls" controversy...the same thing happened surrounding the movie "Dunkirk" earlier this summer.
There were protests that there were not enough women and "people of color" represented in the film. Sorry, but it was a WAR movie set in the 1940s. There were no women in combat roles at that time, nor a lot of "people of color" in either the British, German, or French forces.
