Comon spidey isnt always a cheesy wise cracking moron, hes at his best when he is, but theres more to the character than that. specially if one needs to fill a film.
He wasnt laughing when uncle ben was shot, gwen went sky diving, ben reilly trolled him ( fucking wasted my money being subscribed to spiderman during that arc ) baby may was kidnapped, married the symbiote, became the target of kravens safari. he was mighty serious.
dunno why film makers cant pick up such great stories ( minus the troll/clone saga ) instead of going for the origin.
