Problem is, they wrote themselves into this corner by making "Mr. Stark" his defining characterization and the single most important character in the Spider-Man MCU movies. What should've been done is that he interacts with multiple heroes, Iron Man of course, but also bonding with Cap and having a friendship with the others. I'd like to see a scene of Spidey and Hawkeye bonding, getting introspective on both, perhaps like this in Secret Wars:
However, he only interacts with Stark, and anything else is brief and token, amounting to a few sentences. Strange outright calls Peter his "ward" and nothing is done to combat that. This is before you get into Iron Man's "below my pay grade" attitude, which was insulting (Avengers have dealt with plenty of street level villains in the comics), dumb (Vulture was a huge threat both to the Avengers and to the people with the weapons he was trafficking), and worse, he was painted as being in the right somehow. If Spidey had died at the end at Vulture's hands, it would've been entirely his fault.
Let the record stand that I still enjoyed the movies, but Stark was a weak link. Unfortunately, because he's so prominent in them, that amounts to a lot gripes.
I also like the idea that Spidey couldn't make an accurate Ditko suit on his own, yet he could still build fully functional web shooters. Then he
did make his own suit, albeit with Stark resources, but the bottom line is that both of these undermine the idea that "Peter couldn't make his own suit".
Also, I was actually looking forward to Nick Fury in FFH. I thought it would've been great to switch it up, exchange snark, and have a relationship similar to that of Ultimate. Plus, it'd be a nice break from Stark, while going with a memorable comics relationship (alternate universe, but still). Yet that was mishandled too. First, Nick Fury just pulls him in a mission with no agency of his own. Second, they don't have much of a relationship at all, just Fury talking down on Spidey, so no meaningful interactions. Third,
that wasn't even Fury! The real Nick Fury thought so little of Spider-Man that he sent a Skrull double just to take of him like he was some pest, while he was on vacation at the S.W.O.R.D. base. Just insulting. I mean, Nick Fury was a hardass in USM to Spidey, but he did actually care about him, and certainly enough to
show up in person.
