Okay, one was a tongue in cheek gag, one wasn't. One was an element of a carefully thought sequence (ie. done for real), one was an afterthought (ie. CGI). One was an extension of character, one wasn't.
 
Y'see, Bond actually fights for England as part of her majesty's secret service, whereas Spidey is supposed to represent the everyman.
 
Anyway, it's not like I passionately hate the shot, I just can't see any of the logic behind it's inclusion.
		
		
	 
 
So, if an element is cg, it must be an 'afterthought' instead of a 'carefully thought out' way to make the flag look exactly the way it was meant to look or allow people who didn't want to see it in that shot to remove it (because the director, though knowing he had every right to put whatever he wanted in his film, had enough forethought to realize that some people would whine about the presence of the flag and make an easy way for it to be removed if necessary)?
 
An extension of the character? Oh, you mean Bond. Who actually fights for England. As part of her majesty's 
secret service. Who had just narrowly escaped death from enemy agents, is trying to get out of sight, plunges off a cliff, and so inconspicuously pops a red, white, and blue Union Jack parachute so that any other agents in the area would have no problem spotting him! Exactly what the intelligent Brittish superspy would have done! 

 The last thing Bond would want is that big flag chute clearly marking his presence and location. It was done to gratuitously link Bond with Brittain. But I think you said that you're English, so that's alright then. America+Spider-man = Nooooooo! Bond+Brittain = Ok because you're English. Good one. 
 
How exactly is Spider-man more of an "everyman" than Bond? A nerdy genius who can climb sheer walls and shoot webs from his hands I'd argue is less an everyman than a suave English secret agent.
 
As to your last statement, I guess I took your comments about American flags in an American neighborhood being intimidating and how the only good the American flag in the shot we're discussing could do is piss off the rest of the world (you know, everything else that isn't in America) to mean you just had a problem with the American flag, but I guess that your position about the flag 
really is only how you think its inclusion in that shot is illogical. So I refer you back to my earlier staement: Americans like to see Spider-man linked with the American flag because he's American just like Brittish people like to see Bond linked with the Brittish flag because he's Brittish. 'Nuff said!
