If the majority of fans dislike it then he should stop it. Please the fans should be #1.
Uh, no. You can't give the fans what they want, cause then they'll never be happy till you've catered to them to the point that you've trashed the franchise. Usually what they want is bad for the franchise (see: business). Even if you concede to their wishes, there'd be a very vocal minority that would bitch and complain like spoiled brats.
