People often wonder where mass gunners come from … well, here's the explanation.
Consider this fact in the movie: The Joker would not have been a killer if a fool had not granted him access to a weapon. No weapon, no murder.
Therefore, this film is of great relevance today when American citizens make decisions about their government and especially about weapons.
Imagine an alternative end for the Joker … he gets a licensed psychiatric treatment, or a fool gives him a gun. Which end would you prefer?
"Joker" reflects the real life. So, if you want to be entertained by an "action movie," I could see your disappointment.
