I don't think anyone accused Will of being arrogant, just that he got incredibly boosted by the judges. His fault? No, but it was bound to have a backlash.
I think the criticism that Danny got last season from some of the judges actually helped him in the end come out of his shell and project more. Will never received ANY criticism and I think that was a disservice to him. It was always Jessica's fault, and when she was gone, the praise was just downright embarassing (Cat, get OFF the floor- sheesh!).
I think the viewers like to find their favorites, not have them crammed down their throats!
Having said all that....I LIKE Will and hope he is signed by some incredible group.
