How far should a franchise go away from it's original formular?

Umm.... you do know that the last couple of Final Fantasy games have divided the fans further than ever before. 

 

Every game in the franchise has been divisive. The latest ones just deepen this factor, but as far as I can tell, everyone ended up loving them all.

I think 13 actually is generally viewed as downpoint by the majority.  Honestly the people that love 13 are the ones that loved it from the start, and are vocal about it. It was also one of the poorest reviewed final fantasy in a generation where reviewers inflated everything.
