Re: *Spoilers* Problems caused by the MCU
I didn't like Iron Man because it was grounded. I liked Iron Man because the characters behaved like real people. It doesn't matter how fantastic the threat is. As long as your characters have a realistic response to the fantastic elements, its fine. This goes for Nolan's Dark Knight trilogy, too. It isn't realistic at all; the characters simply respond like real people would to the events of the trilogy.
"Never call him that!" Spittle sprayed from Theon's lips. "Ramsay Bolton, not Ramsay Snow, never Snow, never, you have to remember his name, or he will hurt you."
"He is welcome to try. Whatever name he goes by."
