In my mind the only thing close to a solution for Disney/LFL is to move entirely beyond the existing characters, so at least there will be one less factor that comes with a lot of emotional baggage for fans.
Or, you know, they could have treated the legacy characters right. Never getting to see the big three reunited just one more time on screen will always be unforgivable. That is one area the ST bungled from the beginning.
Well that certainly is something that they could have done to appease fans. But a lot of people think the legacy characters have been served very well (and appreciate that they’ve been given a story that didn’t necessarily have to fit the obvious fan service check boxes). Served “right” is incredibly subjective.
Tying into my point here, I think that if decades of pent up fan hype wasn’t part of the equation, then this wouldn’t be as big a problem for some. After all these years, it’s natural for fans to have very specific ideas of what “serving a character right” means.
