Not everything is postmodernist. Not even everything you dislike is postmodernist. Some things are not postmodernist.
Artistic license is not postmodernist. It has been around for a long time, longer than postmodernism.
Why am I telling you this? Because of some literal-minded bozos who have been complaining that a Hollywood movie about Noah and his big boat CHANGED SOME OF THE THINGS IN THE STORY.
At the request of the National Religious Broadcasters (NRB), Paramount added a disclaimer which reads, in part, that “[t]he film is inspired by the story of Noah. While artistic license has been taken, we believe that this film is true to the essence, values, and integrity of a story that is a cornerstone of faith for millions of people worldwide. The biblical story of Noah can be found in the book of Genesis.”
