When I saw the movie in theaters I also noticed that Spidey is somewhat a sidekick or acts like a sidekick.
I think people find it weird that Peter tries to impress Tony too much, which is not what we are used to. Spidey usually just dashes in to fight the villain. If he gets beaten he restrategizes.
In this timeline Tony helps him with his suit, which turns him in to the goto person to ask for advice. 16 year old Peter had no hero to ask for advice. By the time he started encountering other heroes he already developed his fighting style and gadgets.
The movie was great it would have benefited from a slightly less focus on Tony, but other than that it was cool. (that said Tony was still cool, just overused)
What I'm saying is that there were some aspects of Spidey's growth as a solitary hero that were sacrificed.
However I really liked the final scene where he refuses the fancy suit to find his own way. That's the Spidey I know and love.
