YMMV / Lethal Weapon 4

• Big-Lipped Alligator Moment: The opening scene, which has Murtaugh and Riggs fighting the Human Tank, AKA some guy in full body armor running around with an assault rifle and a flamethrower. This has no bearing on the plot and is never referenced again aside from a newspaper clipping in one scene. Fans like to joke that a Batman villain wandered into the wrong movie because of his similarity to pyromaniac villain Firefly.
• Ensemble Dark Horse: The film introduced American audiences to Jet Li (or at least to the audiences not familiar with Chinese/Hong Kongese martial arts movies), and his character is largely what makes that film watchable. Many American moviegoers left the theaters saying, "Who the Hell was that?"
• Harsher in Hindsight: Mel Gibson's character getting "married" by a Rabbi, given all his anti-Semitic moments that emerged.
• Hilarious in Hindsight: In what also counts as Technology Marches On, at one point Butters complains about cell phones getting increasingly small, and indeed the one he's holding is quite large compared to how they looked in later years!
• Moral Event Horizon: Wah Sing Ku crosses it when he strangles Hong to get his uncle to cooperate. Then he kills his uncle after the counterfeit plates are completed and Uncle Benny for revealing too much information.
• One-Scene Wonder: The Human Tank in the intro.
• Rooting for the Empire: Just try not to cheer for Jet Li.
• Signature Scene: The car chase on the freeway, it was the most advertised scene of the movie.
