Ok,
as a long time fan of EU books (The Truce at Bakura is in my top 5 books I re-read to death pile) I agree that some of it can, at times be silly (an ex-imperial admeral becoming leader of the GA, c'mon, really?!), at times, undermine its own mythology (are jedi telephathic or not, make up your mind EU writers!) and often just gets to complex for its own good (One day I will understand the Legacy of the Force series' plot). BUT! Sometimes it just tells really excellent stories staring characters that you can get really invested in.
Is it rediculous that I hold Han and Leia's marriage as an example of how to do it right? Actually no, because a group of writers over the years have poured their own interpritation of what Han and Leia's relationship is all about creating this wonderful narrative. That's good characterisation, even if it's got 'Star Wars' on the cover.
Will I be sad that teenage Ben Skywalker, adult Jaina Solo and Master Saba Sabatyne won't show up in the new films, yes, because I love those characters but it doesn't stop them existing!
As an aside, the Fate of the Jedi series is Star Wars at its best, it manages to strip away most of the over-complex plotting, get back to the characters and use a glaxay far, far away to explore ideas of selfishness vs. selflessness, good vs. evil, moral relativeism, farther/son relationships and everything inbetween. Sure, it's EU but I dare anyone to tell me that its not well-written and isn't fun. Afterall, Twilight is badly written and people love that story.
With any luck someone's going into this new project with an idea to explore or a story to tell other than just 'let's make another Star Wars film' because that's when things are rubbish.
What I don't want to see is disney feeling like they have to throw us a bone and just bring in a character for the sake of fan service, that would be stupid. (On a serious note, is this thing going to be live-action?)
