The hell?
This is the same defense used for ASM. Just wait for ASM2! That's obviously what they're building toward! A long-form arc.
FYI, Peter had just as strong development in SM1.
A perfect example of the difference of Peter in SM1 to Peter in Homecoming is that Homecoming Peter feels entitled to Stark's super-suit that does everything for him.
In Spider-Man 1, a (again, broke-as-fuck) struggling Peter Parker is offered help from Norman Osbourne, who offers to make a call to get Peter a job 'It's no problem. I'll make a couple calls.'
Peter's response? Thank you. But I like to earn what I get.
Osbourne's (who is the fucking villain of this film) then displays a quiet admiration of Peter: You want to make it on your own steam. Good for you.
So no. When you have 120 minutes to tell a story, and you can develop the moral compass of your character in such a short amount of time, saying 'Just wait for the second movie' is not a valid excuse imo.
You're comparing a college freshman's decision making ability to that of a high school sophomore's.Fine.Lets ignore the hypocrisy of Rami's Peter wanting to "make it on his own" even though he's living in a massive Manhattan apartment where 90% of the rent is payed for by Harry's Dad. At the end of Homecoming Peter makes the same decision and turns down his pseudo farther figures offer for help in order to "make it on his own".
You keep bring up bringing up the ASM franchise as a valid comparison for what to expect in sequels and character arcs when it isn't. The MCU has spent the better part of a decade establishing itself and it's characters so when they leave some aspects of character develop for future movies I trust them. The Rami films are great but they weren't perfect. Same is true for Homecoming.
