I would say you can attest people to just hearing the name 'Bourne' and automatically liking it and being interested. After all, did it go out on a bad note? I think not. HOWEVER the same can not be said about Spider-Man 3. General audiences for the most part hated that movie thus we're without a doubt going to see what happened to 'Batman Begins' happen to 'The Amazing Spider-Man.' I say this because marketing has nothing to do with Bourne, I mean - what? It has one trailer that I have yet to see except for one time in theaters (and I go two to three times a week, sometimes more). That's marketing? I don't think so. That's brand recognition. Something Spidey at this point has going against him.
That said, like all films, it's going to be a blitzkrieg once we get down to it. They're going to be pulling all the stops. Yes, you can say those posters are like the other films. But, dude, seriously - you do know at this point only fanboys have seen those right? Not general audience members. So it really doesn't fly into the face of anything other than all that's going on right now is brand recognition. We'll have a true knowing point once we reach June. But definitely not before. And to put Spider-Man promotions largely out when Avengers is out? With a general audience that only knows of it as "the movie where all the heroes come together" - it'd without a doubt get lost in the mix. Most likely, they'd get confused cause' as we know some already are.
And for those who think brand recognition has nothing to do with what's gonna inevitably happen... dudes, seriously? BATMAN is brand recognition and all people kept thinking when BEGINS came out was "uh-oh, Bats movie after B&R gotta be cautious!" Spidey won't be immune to that. I'm looking at same kinda numbers due to that. It's going to do good. But, even SONY is expecting a blow back from SM3 in getting audience trust back. Then if trust is earned, like with BB, expect TAS2 to be the major success again.
