In the movie Paterson, the titular character doesn't appear to me to change in any way during the movie. At the end of the film I was left thinking, "Well that was mildly interesting. What was the point of that?" Then I remembered the movie Adaptation.
In the movie Adaptation, Nicholas Cage plays a screenwriter (or 2) who at one point attends a screenwriting seminar. During the seminar, he tells the presenter that he wants to write a movie where the main character doesn't change. The presenter basically tells him, nobody wants to see that movie - there's no point in writing such a screenplay.
Did Jim Jaramuch make that movie in Paterson? If not, how did Paterson change or grow? Even more than just whether he decided to make copies of his new poems, did he change in any way at all?
