I guess it's possible you are correct and like the bulk of people who have ever studied film, literature, and art more generally are wrong. That seems unlikely. More plausible is that it's common for people to experience a given work multiple times and get different things out of it.

That's not even accounting for the "Reading Lear as an old man hits differently than reading it when I was a teenager" factor. That is, who you are changes over time and that affects how you experience art.
