I agree with alot of the things you said, I also have a few points to make of my own.

I think although you are right in many ways, the older FFs had less room to make mistakes as they were very basic, and were just simple and fun games.

I also think that it's unfair to say people boycott FF games for being original, although I'm sure this is true to a certain extent, just because something is original, doesn't make it good.

That last statement wasn't reffering to any particular FF, I think they are all good.
