Maybe. Though the odd thing is, Ra's al-Gul has always been caucasian; the "fake" Ra's was the one with the changed race. As for why the massive ( fan ) reaction against the Mandarin twist? I have some theories about it, but none of them really satisfy me. 1. "The Mandarin looked like he'd be a dark, serious villain in the Joker mold. Then he was revealed to be just another pulp world conqueror." Possible, but iffy. The backlash feels more like offended Marvel fans, who shouldn't have been expecting a Nolan-esque plot anyway. Besides, I tend to see a lot of disdain for the numerous Ledger Joker clones amongst fandom these days. 2. "Killian isn't true to the comics!" Only works if you assume the fans in question are completely clueless, as the Kingsley Mandarin has absolutely nothing to do with the comics version, even less so than Killian. I'm certainly willing to believe there are clueless fans who believe something that makes no sense on even casual thought, but this loud and persistent a rage, with its implied numbers of outraged fans? 3. "Shane Black lied to me!" No, he didn't, not anymore than any other trailer, really. I hear a lot of complaints about trailers always spoiling, so why get outraged when a trailer actually doesn't spoiler for once? Also, it makes little sense why *this* deceptive trailer would set off the outrage. 4. "I actually don't mind Killian, but I hate that Pepper killed him! So I'm going to complain about the Mandarin twist rather than admit to my misogyny!" I am totally willing to believe that this is the underlying reasoning to not a few of the outraged fans. However, I've seen plenty of people complain about the Mandarin, who also at least claim to like Pepper fine. Maybe its just a perfect storm, of a whole bunch of largely unrelated meme strains that happened to coincide at once?
