I don’t agree. Yes, every work of art is open to interpretation, but that interpretation has to be informed by the art. There has to be supporting evidence and you have to consume the art holistically.

You can’t, for insurance, conclude that the meaning of The Princess Bride is that Sicilians are dangerous when death is on the line by focusing solely on a single character’s words, ignoring the fact that he is outwitted and dies, and ignoring that the book is primarily not focused on that character. I mean, you can; but then you definitely haven’t understood the film/book.
