Waxing philosophical, every IP is a hit away from relevancy again. Star Wars is no different, fans tend to look past the stinking poo patties to the newly sprouted petunias, a little stench is to be expected now and again. Most fans carry prescription rose-colored glasses by fiat. However, in the absence of petunias, problems abound.
I'm of the mind, that some of the angst has more to do with the misuse of characters, and by extension the actors, in a one-shot-to-get-it-right opportunity, given the age of said actors. Disney appears to not only to have just missed the mark, but failed, because now that opportunity is gone, without some hefty CGI or lawyers. As said characters and/or actors are now deceased. I really think that's the crux of it. Who willingly writes themselves into a corner the way they did? On principle, I would have fired someone. The older characters should have passed the torch to a new group of characters, for more stories, not sure anyone even cares about the new characters?
I'm sure the final installment will look fantastic, but that is about it.
