I do think the audience needs to be more accepting of superhero reboots. I also think the studios need to be more respectful of the properties being rebooted. WB had a great thing going with Batman, because even if it varied distinctly from the comics, there was an unmistakable respect for the source material, which was embraced while still making the necessary adjustments to allow the franchise to work to its full potential cinematically. It was a formula the was discarded to a large extent with Man Of Steel, which seems to be a movie that embraces Batman's legacy but showed no respect to Superman's. The same argument can be made for Ang Lee's Hulk. I'm not sure it can be quite so clearly made with Daredevil, which was done better than many people want to give it credit for - but in the end just wasn't very enjoyable.
As for Spider-man, I agree with Mets that re-introducing OsCorp was a miscalculation. I love many things about the new Spider-man movies, particularly his fighting and verbal style. But I have no interest at all in the tenuous relationship between every blasted character in the story and OsCorp. The Green Goblin isn't as essential to the Spider-man mythos as Joker is to Batman. Peter's character out of costume seems hesitant, as if the creators really know about Peter or are in agreement what his personal life is like and how he will react to certain circumstances. The only person who really seems to have a handle on it is Garfield, but he isn't given sufficient material to pull it off.
