It’s similar for me. I was really looking forward to seeing Rey and Finn and Poe’s story continue in 8. And really, really looking forward to seeing Luke again in 8. That excitement is pretty much all gone now and I’ll be seeing 9 out of morbid curiosity and to see if JJ can bring any real closure to the trilogy for me.
It’s sad to think that it has come to the point that many SW fans despite their reservations and opinions will go see this film just for the fact that it’s the last of the saga but not fully invested in the concept anymore.
I guess there comes a saturation point, I mean IMO the same happened with me and the Star Trek franchise of films along time ago. The magic is gone
