Actually thinking on it a bit more (And partly cause of that Solo thread), the biggest change to my relationship with movies is that I've just stopped caring about the rumours, and the fan theories, and the hype and all of that bullshit that happens in the lead-up. It just doesn't matter anymore, that incessant back and forth between being pissed off or excited about some random bit of something was just exhausting or infuriating and gained me absolutely nothing. So that's just started phasing out of my thought process. Obviously I still get hyped and excited for movies, but not the specific theories or rumors or little details of the lead up of the internet hype/anger machine. Side along with this I've also pretty much stopped watching trailers, I'll watch the first one if it's something I'm interested in, but after that I just don't care.
That was a big shift for me in my relationship to the new Star Wars especially. There is literally nothing I can possibly do to influence or change the decisions being put into those movies. LITERALLY /NOTHING/. So I've pretty much just stopped caring, and I'll go into the movie and see what they decided to do with it. If it works cool I have a new movie I like, if not, then I can dissect it and learn from it, but anything before that point is just unnecessary emotional wear and tear.
I think this is also just part of a general trend I've noticed in myself of trying to cut out the unnecessary cynicism and negativity. I'd infinitely rather be super excited and jazzed for things I like, than shitting on and bitching about things I didn't. It's just way more fun.
