About being "absurdly whitewashed."  Well, if it's a problem for anybody other than reviewers and the  finger-pointing outraged, people won't pay to see the flick. When enough die at the box-office, then whitewashing will stop.  If not...it won't.

Did Brits scream outrage at misappropriation because a Yank star (Gregory Peck) found his way into British-in-Burma war movie and was passed off as a RCAF officer to explain his lack of British accent (1954; "The Purple Plain")?  Did Canadians scream outrage when Yank star Cliff Robertson, played A Canadian C.O., did Americans scream when Brit Michael Rennie played a US C.O. (1968: "The Devil's Brigade")?  Did the Japanese complain when the Seven Samuri became Magnificent Seven? Did Mexican government demand an apology when Warners created Sleepy Gonzales? Did Canadians rise up at decades worth of American "Mountie" movies and TV shows?  No Screams.  Just a few chuckles and sneers.  

All this stuff only matters to a few.
