Although, I would say there may be fans who have come to Bon Jovi in the last 15 years based on the modern music. I find that a stretch to imagine, but those types of fans must exist and see the older music as worse.

And criticism is a part of liking something. I like only four albums from Bon Jovi, but I am not sure that makes me less of a fan than someone else just because they collect memorabilia or like everything ever released.
