I think now might be a good time for Star Wars fans to watch the Harry Plinkett Review of Abrams' first Star Trek film. To be sure, it doesn't pan the movie, but thoroughly explains in the plainest terms that the desires of sci-fi properties' fanbases DO NOT factor strongly into the creative decisions behind the making of these kinds of blockbuster movies. At the very least, it might get people who are on the fence to not waste their money.
As much as I love the early Star Wars films, I really can't get behind the franchise/brand anymore. Just like Batman, Superman, X-Men, almost every rock/pop act that was good in the 1960s-2000s, Final Fantasy VII, etc..., the expectation bubble on Star Wars burst early along the way and people just seem reluctant to let go and embrace new properties. I certainly understand how hard that can be. It took me about a half-dozen of those awful Expanded Universe novels and the first two prequel films to finally let go of my hopes that the Star Wars universe would somehow be treated with respect I had given it as a dedicated fan.
Thinking on it now, I almost wish that properties like Star Wars, if they must stick around, would operate in a similar fashion as the Final Fantasy game series, where common themes/elements/tropes carry from iteration to iteration but where every new 'edition' of the property starts with a completely clean storytelling slate - new characters, new plot, etc.. Seeing these new movie series stumble along trying to balance fan service with the old characters against the demands of telling a good story with brand new characters has done nothing but bog the stories down completely. Part of what made the original Star Wars work was that it was all NEW. Lucas and company didn't have to feature a bunch of cameos by washed-up and elderly space heroes of days-gone-by (which at that time would have been played by actors the ages of John Wayne, Katherine Hepburn, Charlton Heston, etc...).
That said, I'll happily do without seeing this upcoming hipster-casted Star Wars movie where Han, Luke, or Leia might suffer an ignominious end of the sort that Captain Kirk suffered when they shoehorned him into Star Trek Generations. I'll just assume that one of them gets cut down by Darth Cumberbatch (a.k.a. a go-to for villains that matches Abrams' status of go-to sci-fi director) and look forward to the far-more-entertaining tidal wave of criticism, outrage, and internet memes that follow.
