You see how a single term shuts down your ability to appreciate what he’s saying?
To some extent we do make our own reality, which I think is well illustrated by your reaction to what is a term of literary criticism. I understand objecting that the term is overused or misused, but that’s an argument related to specific usages.
For some this is just a fun popcorn movie. For some it explores deep themes. If it’s all about seeing whatever we want, good or bad, well of course we can do that.
But then so many disagreements are rooted in just wanting to see the film as we want to see it. This relativism appeals to some more than others.
