i wonder if, in the event they do suck, people just think, "well, they WERE good" and we can forget about them, and just maintain that the Lucas years of Star Wars were "the good old days" and those will be the times that people pay attention to.
I don't think that there is a way that Disney could screw it up so bad that i could just "be done" with Star Wars. It will always be there, even if it is an era that has ended with the purchase of LucasFilm. From the beginning of Star Wars until the day that Disney took over will always be there for people, even if the new stuff isn't.
However, i have been wrong before, if there is a way to make a movie so bad that it will make people abandon a franchise, Disney can find it.
