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.

Ive played every single FF game. Even most of the spib offs. And I do not like 13. I hated 13. HATED IT.  And thanks to the bitter taste 13 left in my mouth. I didn't even give 14 a second look and I loved 11. 

I hated 13 so much that I didnt even bother finishing it.
