Seen as this has devolved into 'Girls in Movies again'...
I'm against gender-bent reboots. What's the point of releasing the same movie when all that has changed is the gender of a character? To me, it means nothing about diversity. Ghostbusters is as much about the characters played by Murray et al, as it is about anything else. Changing their genders doesn't work for me. I feel similarly about changing the race or sexual orientation of characters who are already established. No black James Bond please.
Having said that - and assuming you can all get past the inevitable rage at the above - I DO firmly believe there should be more female and ethic minority leads in movies, comics, TV shows, whatever. But this needs to be done with fresh, original characters with their own history and their own characteristics appropriate to the actor/actress in the role.
To this end, I think Jyn and Rey were brilliant introductions to the franchise. We had Luke, Han, Obi-wan and Anakin and they were great. Well, maybe not Anakin. But these look great, and I can't wait to see this movie.
TL:DR - Jyn good, movie looks good, hurry December.
Racebending already happens enough when characters are whitewashed. Ghost in The Shell, for example - OK, Kusanagi is a cyborg, sure, and a white actress playing a Japanese brain in an off-the-shelf-with-some-upgrades full body prosthesis would be clever. IF Hollywood hadn't had a long history of simply erasing Asian ethnicities. I agree with George Takei - write a character that shows what you want them to show. Don't fiddle with it because it'll score you diversity points.
Shows like the Expanse do it right. The book says we need a 6 foot Polynesian woman with muscles. We go find a 6 foot Polynesian woman with muscles.
When I write my characters, I don't tick checkboxes. I don't have to tick checkboxes because I have all kinds of diverse people to draw inspiration from. You want an interplay of sufficiently different people to give your story volume.
Also, you know what my wife's comment was?
Star Wars is too human-centric, including Rogue One.
