Let's be honest people, most, not all, but most people didn't give a damn about the Mandarin until they saw the first trailers for IM3 then everyone went on Wikipedia, read his bio, found out he's considered Iron Man's greatest foe and now, he's, all of a sudden, a Joker, Venom, or Lex Luthor tier villain? He's not, he's an outdated caricature of Asian stereotypes. And if you were a Mandarin-fan before the trailers, there's a damn good chance you became a fan after seeing the first Iron Man and got yourself invested in the Iron Man universe because you fell in love with RDJ's portrayal of Tony Stark. And then there's the true purist who have been die-hard fans before the first Iron Man movie who may have a legitimate beef. But please don't bring comic book accuracy into your argument. This is the Marvel Cinematic Universe, it's not intended to be 100% comic book accurate, hell no superhero movie is. I personally applaud the writers and producers for making this bold move (remember Joss frikken Whedon has to sign off on the movie meaning he approved the twist, you wanna argue with this guy? I repeat, you wanna argue with Joss frikken Whedon about superheroes-related topics?!)If you're gonna nit-pick certain inaccuracies and twists, while ignoring others, like Jarvis being an AI rather than a butler (hell I think Jarvis is as iconic a comic book character as the Mandarin) then go look at grass, there's never any huge surprises with grass. It's always constant and just grows, no twists no turns, grass will always do what grass is suppose to do. Kevin Feige, Shane Black, and Joss Whedon won't, they like to shake thing up. And be honest people, Mandarin's not that iconic of a villain. Tony Stark/Iron Man has become perhaps the most popular superhero today because he's one cocky S.O.B. who'd tell Batman to get over his dead parents and stop being such a little pussy, not because of his 'amazing' rogues gallery.
