Here we go again...
It's overrated for you. For people who expect to experience the full FF VII story in one game, it definetly isn't. They will have to buy God knows how many different games. Each entry is gonna be a full game, we get that. And that's great for people like you who only care about how much time they can invest into this episodic experience. But for many other people, wondering how many games they will have to buy and how many years they'll have to wait for each one to launch... for a remake of a game that launched as a single title is definetly a major concern.
Just to add to your point, I can’t help but think about the Hobbit movies.
