The movie and the book share a title and the name of the main character. That’s it, and that’s FINE. I love the movie as a dumb Arnold movie. I enjoyed the book as a dystopian romp. It has been probably 25 years since I read it but it does say interesting things about how the media controls the narrative. The ending is of course super dark and feels problematic after a certain event which happened long after the book was published.
