Yes, there's early bloomers in HS, but doesn't that go against the Peter Parker persona? Isn't he supposed to be the weak geeky kid who gets picked on all the time? So, how are audiences supposed to believe that when he looks older and taller than everyone else? Atleast Tobey Maguire was short and had a dorky face.
Yeah, that is a very good point, that is a problem for the persona of PP.
I recall one guy at my school, who actually is a Garfield type, who was a very quiet type, but tall for his age, someone in the year above us tried picking on him, and he kicked their ass.
I suppose it would be more of a problem if it was an origin movie, when someone picked on him pre-powers, we could think, even unconciously, 'this guy is pathetic, he has the height and build, and shrinks back and allows himself to be bullied?! and this guy is the superhero?!!'
but if the movie is set *after* he gets the powers, and he shrinks away from the bullying, we will all just think, 'he doesn't want to fight them because he doesn't want them to find out he's spider-man'.
I know what you are talking about, but it may not be as big a problem as that. It depends how he carries himself as well, whether we believe he is a meek hs student.
