Like ray_afraid I too am a bit indifferent, ever since the special edition DVDs about 10 years ago i pretty much stopped watching Star Wars. Only until I found this forum (and a few other things) has my interest been renewed.
As far as Ep.7 to Ep.X .. Indifferent, mixed feelings, anxious, nervous, pis--d .. guess I don't really know how I feel. Lets face it "Lens-flare" Abrams has done good movies and was involved in many successful TV shows. But this is Star Wars after all, it's not the same. Like Star Trek, this series has touched and inspired so many of my generation, it's a rather touchy subject to tackle.
He can't tinker with it but he can't just do a rehash either. It has to be interesting, fresh, new and exciting but he needs to follow the established universe as well. He has so many obstacles in front of him, most of them built by us..the fans (and yes the media as well).
In the end, I'll take the movie the way it will be done. And like any radio program or TV show, I'll just change the channel if I don't like it. I had such high hopes when Phantom Menace came out... I won't be making the same mistake twice.
