Well, I can't speak for anyone else, but I'll probably just treat Star Wars as a fiction buffet. I'll pick and choose what I like, and ignore the rest. After about....hmm....I'd say 2008 or so, that's how I began approaching the franchise. I was pissed about all the focus on Clone Wars era stuff (especially, since it seemed to come at the expense of the OT era). Prior to that, while the Prequels were being released, I was more invested in the franchise and consuming more stuff from it, but I gradually just came to realize that the brand that had once stood (for me at least) for a guaranteed good time was now more like a guaranteed mediocre time with the occasional glimpse of brilliance. Based on that realization, I backed off of the franchise considerably (plus, there was less and less out there that caught my eye).
Now I just take what I want from the franchise, and have stopped trying to will it to be what I want it to be, and instead accept it for what it is (and isn't), and enjoy what I can from it.
So, yeah, if this movie sucks...I mean, that's a bummer, but on the other hand...meh. Screw it. There's so much else out there nowadays that I enjoy, I don't need everything to be made for my specific tastes. There's enough already catering to my tastes to keep me entertained.
