Re: *Spoilers* Problems caused by the MCU
"Realism" in the context of this genre doesn't have to mean "dark, gritty, and tragic." Just realistic reactions and responses to these elements of the fantastic and unreality suddenly being dropped in the middle of the real world. It's "realistic" to believe that a lot of people would take the Tony Stark attitude and respond to it all with jokes, wisecracks and one-liners. That's also (*supposed* to be...) Spidey's style and Hawkeye's style.
