Star Wars is the only franchise where my head canon has replaced official releases with fan edits (ie. the Prequels). Other franchises might have fan edits, but they’re basically an alternate cut and don’t affect (for good or ill) my feelings on their respective franchise. With the Star Wars Prequels, I can not include the official versions as the actual events, but certain edits I have seen are good enough to make the stories plausible.

For everything else, I usually include everything, be it movies, shows or books. For example, with regard to Star Trek, I don’t pretend that Star Trek V: The Final Frontier didn’t happen. I just say it’s a stupid movie, never watch it, and leave it at that.
