Star Wars sucks.
Proud to say I have not watched any Disney plus Star Wars crap.
Same here, although I like the first 6 movies, I feel like everything they made after that was capitalizing on the culture with toys, legos, and throwing bad scripts and screenplay at people, hoping they'll want to introduce their children to the saga they watched as kids in the 80s and 90s. On the other hand, these Disney people know how to make money because kids don't want to see actors anymore. All they want is CGI and dolby atmos, which is why Marvel is making so much money with the crap they're making.
The great thing about having your own 'head canon' of certain Universe franchises is that you can mentally include what you liked and exclude what you didn't.
For me:Star Wars = First 6 movies + Rogue One + Clone Wars show +(some of the EU/Legends novels)
Matrix = First movie (the others were an abomination and don't exist)
Terminator = First and Second movies only
Alien = First and Second movies only
etc., etc.
That new Matrix movie. WTF.

But then I didn't like 2 & 3 either indeed. The Enter The Matrix game I remember being pretty good on the Gamecube 20 years ago at least. Felt more authentic than the sequels.
The Matrix Unreal Engine demo on PS5 is pretty neat but there is nothing really to do. Even then, I enjoyed that far more than the 3 sequel movies.
Also the latest Terminator was a disgrace. The Terminator got old, settled down and is in the curtain business. Compare that to the dramatic ending in T2. Seriously?!
T3 was meh with a few good bits: the crane chase and the excellent ending. Had that one been developed a bit more and done by James Cameron it might have been a good trilogy.
At least we got John Wick 4 which is pretty decent, if you like that sort of stuff.

But to your point about what you can consider canon is indeed reality for many people I suspect.
It's funny when Hollywood tries to sort of satisfy that consideration and then fall on its ass even more.
To me Terminator Dark Fate is a far worse movie than Terminator 3, that the latest one tries to ignore (John Connor ending up dead at a young age instead).
