I don't have a problem with female leads or any other deviation from the admittedly predominant 'white male' star. If a part in a story is written for them, then great! Im a fan!
What I do have a problem with, and I hope I dont offend anyone here, is when a role seems to be filled with an unexpected deviation in actor preference.. well just because you can and ... as above... its 2016 and we have to recognize our diversity or whatever.
The recent trend of well known, established and traditional heroes and characters suddenly changing race, gender or sexual preference just for the hell of it is pretty disappointing.
A female X wing pilot? Awesome!
An ethnic Grand Moff? Cool!
A gay bounty hunter? Sure, whatever, fine!
But if a film rendition of "Heir to the Empire" presents Grand Admiral Thrawn as an oriental lesbian... well I'll have to off myself.
This kind of assumes that the "default" position for a hero is male, and/or white to be honest. I don't see how a new story, with new characters, is an "unexpected deviation". I have zero expectation of who the protagonists are, and why, and I don't care. I personally don't care if they never show me another white male protagonist again, as long as the characters they do show me are actually written well. If they're poorly written, 2 dimensional cliches, it doesn't matter what race/gender/sexual orientation they are, they're going to suck, and I'm going to be annoyed.
Besides, an asian lesbian Thrawn might actually make that character interesting. He was terribly over the top with his "oooh, mmmm, I've studied their aaaarht, so now I know their combat strategies, mmmm, yessss." attitude. Oh, and that line was said with a Stewie Griffin accent, for extra sass. Even when i was 12 years old and reading that series, I thought he was terrible. So sure! Bring on a lesbian Thrawn! It can't be any worse than the original!
And there you go. Laugh
My comment on unexpected deviation was referring to what one would expect of an actor picked to play a role where certain traits were already established. (gender, race etc.)
I would be just as upset if Mon Mothma was suddenly a grey haired old man or Lando Calrissean turned white!
Except that your previous comment of "looks like they've run out of male heroes" sort of implies that they should be using male heroes, the way you worded it. It certainly made a point that her gender as the lead protagonist is something of note.
Personally, I don't really care if they gender/race/orientation swap every known character to date in the history of ever. Write a good story with them and I don't care. I have no personal vested stake in Lando being black, or Spiderman being white, or Thrawn *gags* being male. It doesn't matter one whit to me, at all. I want a good story, with good characters that are compelling, and make me empathize with them. If the writers can't do that one thing which is their entire job really, then no amount of "sticking true to the source material" is going to matter. It's a bad character in a bad story.
