'I am nothing without this suit.
Being neighbourhood friendly isn't the only reason so many love Spider-Man. In addition to his tough childhood and his desire to save the world, the fact he does it in skin tight spandex doesn't hinder his appeal. Spider-Man has been a popular costume for kids for decades. There is something about putting on the red and blue that brings out desire to jump around the living room spraying fake webs on every wall and piece of furniture.
For adults, pulling on the spandex is a bit more daring. If you're going to wear the suit, you go in knowing your people's eyes will zooming straight to your butt and your crotch and they'll be judging and sizing you up. My favorite movie Spider-Man was Tobey Maguire, mostly because I never saw Maguire as the least bit sexy until he ripped off his shirt and put on the suit in the first movie. Since then, the web slinger and his family just get younger, especially Aunt May whose casting is getting ridiculous...
