I'm definitely in a similar boat. Not jumping off as in "never see any movies on the big screen again" but rather being content enough with what already exists and the experiences I've already had to the point that I don't know how often I'll ever need to preorder tickets for opening weekend after AEG and SW9 ever again. I see myself as just catching whatever comes up on $5 Tuesday when crowds have died down, I won't be worried about avoiding spoilers for whatever, and so on. I kind of look forward to crossing that threshold, lol.
I've got epic old SW, epic new SW, timeless fantasy (LOTR) and sword & sorcery (CTB), a ton of classic action (Indy, Die Hard, etc.) gritty sci-fi (ALIENS, Terminator, RoboCop, BR2049), and now all these epic superhero flicks. Plus all the great horror, monster, and countless films of all the other genres. Not so much "needs" to be made/remade for me anymore. Yeah I'll be there for Robotech and Gundam if those ever happen, but not much else at this point.
