There will always be these people. Proper gets my goat! You want the unvarnished facts, go make a documentary! This is a film and ipso facto a work of fiction (the medium fictionalises).
All the representation stuff is just duckspeaking, to be ignored.
Mind, the fiction nitpickers are worse! Make a film or films of any given book or books and an ocean of ink will be spilled on what you missed out or did wrong: "Where was Glorfindel/ Hermione was wearing a blue dress in that scene/Dracula could go out in daylight, blah, blah, piffle blot!"
You'd think these folk would have more important things to bellyache about!
