Not you Nam, not you!
There's not much to misunderstand, most people like it because RDJ can carry a film all by himself and he doesn't slack on IM3. If this were it's own original IP, some of the CBM complaints would go away but it's still kind of a sloppy movie with a strange sense of payoff. Still, RDJ is invincible right now so life goes on.
The Mandarin has been deemed a worthless (even hurtful) stereotype and must go the way of complete character transplant. Anyone who has a problem with it must be a racist insular comic book nerd.
So now as part of my racial sensitivity training I can no longer wear corrective vision lenses so I learn what it feels like to squint all the time and I've finally moved out of my great grandparents sub basement, but I had to change out my protective bubble.
Stupid IM3!
