I've done without mainstream Star Wars for about 30 years, so I really don't have a horse in this race. That said; I'm expecting it to be considerably different and much better than anything Lucas could have done. For that reason alone, I'm looking forward to it. I'll go out of curiosity and out of respect for what Abrams has given me as a movie-goer; Super 8 and Star Trek 09.
Abrams brought me back to mainstream\current Star Trek. That's another franchise where I'd long since thought my interest and personal canon had been a completed chapter.
I suppose if I had to come up with a word or thought to describe my views of the next Star Wars film, it would be something along the lines of apathy.
Lucas ruined the franchise for me back in 1983, so my interest has been 1970s Star Wars or EU that respected the 1970s timeline and characters. Anything even close to that from Abrams will be a gift. The original cast is back, as are full-size sets, models, techniques, locations, etc.
All from a director who appears to be a fan or the original feel and story. He's very obviously aligning himself and the film with the 1970s and distancing it all from the prequels. That's a good sign.
I understand people not being excited though. This is a franchise that is extremely contaminated with Lucas' arrogance and near resentment of the fan base. Changes no one asked for, lying about the history and motivation, deliberately squelching the originals, and the total disrespect of the fans by altering the story and then making\selling T-shirts mocking the fans who were upset by it. (Han shot first T-shirts).
Those types of slights by the owner\director are hard to get over. Particularly when they've been going on for over twenty years. The franchise is a colossal mess because of Lucas' megalomania. If anyone can bring respect back to it, it's Abrams.
