Eh. The Game of Thrones things are, at times, sort of legitimate. There was one, less insane, SJW type I was watching a video from, and the main thing she takes issue with is the sort of double standard that comes into play in terms of changing the races of characters from books to tv/film. The point she brought up that I am inclined to agree with is that when certain characters who are PoC in source material are turned white, the old "Best actor for the job" line is trotted out, but when white characters are turned black, White Supremacists are out in droves, screeching that it is an abomination (See - Thor)
However, I would respond that these are two distinct populations. It's not like the directors are in cahoots with Stormfront to arange this, yeah? I suspect the Directors would throw the same line at WS', best actor for the job.
As for Game of Thrones... To me there is a... Certian similar hypocricy. Although again, different populations at all.
To Game of Thrones, we say "Why can't there be PoC Westerosi?" "Because Westeros is Fantasy Medieval Europe." "Well its a fantasy universe! If you can have dragons and ice zombies, surely you can have PoC"
Bible Movies are made.
"SWEET FUCKING SHIT ON A SANDWICH! DID YOU DARE MAKE WHITE BIBLE CHARACTERS!?!?!?!"
But I will say this, for the SJ crowd who haven't read the books, if they aren't happy with Arianne Martell (And I've heard rumors that they cut her, but she's a pretty fucking important character. They didn't announce the Greyjoy Brothers, either. Guess that means the
entire fucking plot about the Dragon Horn and conquering the world is getting thrown out the window. But seriously, I'm sure they'll put her in. She's pretty damned vital to the story) I will be pretty shocked.
Equally, if they do cut her, I'll be pretty fucking pissed.
Because that seems to imply they'd be cutting Aegon VI, as well, what with her plot being so entwined with his.
Which in turn would seem to suggest that they are going to sacrifice a good 50% of the later books plot, in order to make more room for witty Tyrion, KHALESSSSIIIII and STANNIS DA MANNIS.
But again, I'm not going to get too riled up until we've got the full cast list. They didn't announce Ellaria Sand in the first round of S4 build up, and here we are today.
