Uncanny Web-Slinger
Super Freak
Being told about something that isn't as exciting as other things being shown trumps wasting time showing something that can be communicated just as easliy with dialogue.
Ang Lee's Hulk movie spent 147 minutes showing Banner be a scientist when all we really wanted was to watch him hulking out and trashing things. No need for Spidey to go that route.
Scenes showing him as intelligent didn't get in the way of Spider-Man though, the Hulk scenario is about proportion, not enough Hulk to Banner ratio.
