There wasn't enough of it.
		
		
	 
 
Spider-Man 1:
 
-discovery of wall crawling powers
-crawled on wall during Unity Day festival 
-suspended himself on ceiling
-suspended himself under balcony 
-crawled on wall chasing after Uncle Ben's Killer 
 
Spider-Man 2:
 
-crawled on wall during Doc Ock accident 
-crawl on side and top of moving train 
-stuck on wall during bank fight 
-crawled wall saving Aunt May 
-suspended himself in open window 
-stood on the tip of a tower confronting Doc Ock
-suspended on ceiling during final battle with Dock Ock 
 
Spider-Man 3:
 
-stuck to falling debris during Harry fight 
-suspended himself one-handed during Spider-Man Appreciation day
-stood horizontally on wall when he first wore black suit 
-crawled on wall when he discovered Sand Man  
 
that's all I can think of at the moment, but the amount of wall crawling was adequate
