Luther's exposition of Ethan's early retirement had me chuckling
Does he (Ethan) have delusions of being a "superhero?" It cracked me up listening to Luther's sad story of the time when Ethan decided to live a private life with his wife but he just couldn't stop thinking about all the bad things happening in the world and he was no longer in a position to do anything to stop them.
Surely this is more risible than any of the outlandish action stunts (parachuting into Paris?) which put this movie high on the list of mindless so-stupid-it's-funny movies.
