Kinda weird comment. Not that it matters, but in the scene Iron Man brushed Elon off -- He was "politely rude", and the scene (while serving as an ad for Elon) served the film by giving cred to Stark by having Elon fawn over him.
More importantly though, treating someone "as a peer" is kinda a weird criticism? Superheros on TV these days don't seem terribly stuck-up. When other characters in the films seem honest the heroes usually treat them with respect and dignity.
Anyway, thanks for the heads-up that you hate superhero movies, will keep it in mind next time I see one on a plane.
(That scene, by the way, is a perfect example of why I hate superhero movies.)
