I mean, is it really this Final Fantasy that is broken or is it the whole brand at this point? Seems to me that the only thing SE has been able to decently in the last decade is milk nostalgia for the old games with spin-offs.
Dissidia
Theatrhythm
World of Final Fantasy
HD Remasters and 3D Remakes
Etc.
And even a lot of that is divisive or questionable.
And now FF7 Remake.
FFXIV ARR is praised for being a good MMO but it took a whole lot to right that ship. It was total garbage when it launched. Personally, I think giving the MMOs mainline numbers is a cheat, anyway.
I don't think SE knows what to do with the main series. I don't know that we should expect them to be able to make a solid, confident, self-contained FF game that could ever measure up to the classics. They see it as this multimedia conglomeration that is more about branding than anything else. I don't think they really know what it even is beyond chocobos and crystals.
They keep trying to reinvent the game radically, too, making it more dumbed down and more complex at the same time to try and get a bigger audience with each entry. They poor so much money into it, building all these vertical slices, have seperate teams churning out terrabytes of art and assets, all of it lacking any real cohesion or unified vision. It's a big mess.
Hironobu Sakaguchi was really the soul of the franchise and the farther we get away from him the more lost and confused it gets.
A Final Fantasy For Fans And First-Timers my ass.
