You mean spending two whole movies waiting in line all so he could get to be a character who had flourished for decades in a period where Iron Man was a B-lister with the flat-out worst rogues gallery of any major hero?
Iron Man isn't fit to shine Spider-Man's shoes as a character. He doesn't deserve to be Spider-Man's mentor. There are MCU characters who do (Cap, Banner) but not Stark.
The Peter from the comics became that character in TASM #1. Ultimate Spider-Man by Issue #13 at the latest. So there should never have been much time needed to do that.He’s not gonna be the Peter we know from the comics over night,
A single 2 and 30mns comic is equivalent in real estate to about 200 issues or so worth of character development, investment and engagement. You can't waste 2 whole movies on Spider-Man before he becomes Spider-Man.but after the previous movie, he was now in the position of character development to become that.
"Hipster Peter" and "Humorless Whiny Peter" are his predecessors and that's Mr. "Hipster Peter" and Mr. "Humorless Whiny Peter" to you.Plus I’d take a Peter who looks up to his predecessors over hipster Peter or humorless whiny Peter any day.
