[fandom] Does it still count as spoilers when the movies came out decades ago?

So in preparation for going to Harry Potter World Universal Orlando this coming Christmas, Wife and I are watching the movies and reading the books. I would say re-watching and re-reading, except I never actually watched any movies besides Sorcerer's Stone and Prisoner of Azkaban (STILL THE PRETTIEST), and did not read past Goblet of Fire. I know what happens! I just...wandered away. As you do.

Then I spent the summer reading HP fanfic, and now I'm going back to the source.

( So far: Book and Movie 1, as well as Movies 2-5. )
