Cross promotional tie-ins have their little rewards. Case in point: Kellogg is starting up a new deal pimping The Amazing Spider-Man.
Long story short, get some special codes off select Kellogg products and your smart-phone to see early clips. This being the Internet, someone has already done the deed and posted said (brief) scenes online, courtesy of Super Hero Hype:
Spidey, the wise-ass (Not a new concept onscreen if you look back at the 2002 originating film) and whatever that Subway scene is. Again echoing memories of Sam Raimi (The "He's just a kid!" scene in Spider-Man 2 comes to mind).
Heard very troubling things on Marc Webb's reboot but I can't judge it based on these clips, especially the first since Garfield looks like he will be superior to Tobey Maguire in the one-liners department.
