STAR WARS: Is it no longer for my generation?

Rating: Null/10 (16 December 2017)

I'm 49 years old. STAR WARS was the first movie that I ever saw as a child. My mom and dad took my brother and I to the drive-in to see it. That year for Christmas I got a STAR WARS bed spread for my room. I've been a true fan for literally as long as I can remember.
My wife and I took our 17 year old son to the movie last night -opening night. Afterward, walking to the truck, the question was asked, "What did I you think of the movie?" Our son says, "That was one of the greatest movies ever!" He goes on about the fighting and everything. He thought it was too long and a little boring at first but really loved it overall. I tried to be nice and said it was my least favorite STAR WARS movie ever. Then my wife and I start tearing apart every aspect of the movie and saying how much we hated so much about it. The audience said it all really: Not a sound for the whole film. No laughing at the stupid humor, No Ooohs or aaahs. No cheering. Really? No cheering from a late opening night theatre full of adults dressed up like STAR WARS characters? There was nothing to cheer about.
I feel really bad. This is no longer my movie franchise. Maybe it will my kid's franchise? Maybe my parents hated A New Hope but just took me and my brother solely for us as kids? Maybe I should have just kept my mouth shut last night. Our son kept saying that we were being such a bummer by talking about how bad it was and what a terrible director and what a terrible story blah blah.
What should I do? Pretend I liked it and take my niece and nephew at Christmas and go with my brother as planned and get popcorn and say how great it was and have a great time with my daughters too as we have planned? Should I do what the professional movie reviewers have done and rave about it even though I know it's a terrible movie on its own and a terrible betrayal of the franchise?
At least my wife and I can be honest with each other. I feel so bad sometimes for this generation growing up now. They don't know how good we had it growing up, and now they have lost the old STAR WARS universe that we had hoped was revived for them to enjoy. Or maybe I'm just old and they will love the new universe being created? Maybe it's time for me to just talk about the good old days and wear my old shirts and get cranky.
My new shirt: STAR WARS: (until Rian Johnson)
