Yes, but that's because like any long running franchise, FF suffers from the Zelda cycle (well until Breath of the Wild actually broke the cycle).

So generally, the last entry is always the "worst" entry. At least until some time has passed and we can evaluate it better. With that said, FFII and VIII are still black sheep entries, and I have no doubt XIII will also stay in this category. I honestly feel XV will probably go up in it's standing once some time has passed and the raw emotions about it's troubled release have subsided.
