Also to further this - look at what happened to X-Men:First Class. Very well critically acclaimed and I have yet to hear one bad word about it from general audience members YET it brought in the least money of all X-Men films and X-Men 3 performed very similarly to Spider-Man 3. Most of it's money coming in that first week due to X2. And then First Class got even lower - due to Wolverine most likely.

Having a bad superhero film in a franchise, despite a somewhat reboot? It didn't work in Batman's favor. It didn't work in X-Men's favor. I'm just not getting my hopes up for Spider-Man because I have no idea how it'll be that different. You're saying the film will rock, that's for granted - I agree. But so did First Class and Begins, that didn't help - audience was still wary. For these films? As First Class 2 will show. You earn back the trust - then the second go around you can earn gold. Look for MOS to show similarly most likely. This happens time and time again. And I doubt there'll be an exception.
