To be sure, I loved the film when it came out. I enjoyed it for what it was — a fun action romp.
But now some 40 or so years later I recognize it as perhaps the beginning of this downward slide that popular films have been on: films that are no more than a stitching together of action sequences — storyboard movies.
Characters are 2 dimensional, don't change or grow across the film arc, morality is black and white....
I saw one of the "Pirates of the Caribbean" films and was confused several times as to if the film was about to end. An epic battle/action sequence would build and conclude and I would assume we were at the denouement. Alas, no, we had merely wrapped up action-sequence #13 and there were still epic battles to come. (I suppose I should have had a clue since we were only at the 2 hour mark.)
