YMMV: Lethal Weapon

  • Acceptable Ethnic Targets / Values Dissonance: Riggs and Murtaugh are vehemently anti-apartheid and take on Amoral Afrikaners in 2, but in 4, seem to think it's perfectly okay to make Asian Speekee Engrish jokes throughout.
  • Awesome Music: The score was co-written and performed by Eric Clapton. Do the math.
  • Big Lipped Alligator Moment: Riggs tricking Murtaugh into taking his clothes off, running out into the street in just his boxers, socks and shoes, and dancing like a giant bird, supposedly to distract an arsonist with a flamethrower, and then admits he only suggested it to see if Murtaugh would actually do it, which leads to Murtaugh being humiliated for months. Also counts as Took a Level in Jerkass - he was never above pranking Murtaugh before but even for Riggs that was pretty low (and just makes it more awesome when Murtaugh punches him later in the film).
  • Complete Monster: Pieter Vorstedt. He crossed the Moral Event Horizon before the first film when he watched Riggs' wife die from her injuries, thus revealing himself to be the Bigger Bad behind Riggs' descent into suicidal despair and mental instability in the first film and only gets worse from there.
  • Contested Sequel: Whilst the first two movies are by and large considered buddy-cop/action classics, 3 and 4 are much more divisive. To some they are installments that have reached the point of self-parody in terms of their level of goofiness with things like the continued presence and pushing into center stage of the Leo Getz character as well as not having as strong of scripts after the departure of Shane Black. Whilst to others they while not as good as the first two are solid entries that continue to show off the great chemistry between its leads, match if not up the ante in at least some of the action scenes, and rounds off the story-arcs of its characters well. Particularly Riggs who finishes his progression from a crazed suicidal man to a more down to earth and at peace guy who can move on with his life and allow himself to be happy.
  • Crazy Awesome: Riggs, Riggs, Riggs.
    • Also, Riggs.
      • "You think I'm crazy? You think I'm crazy, I'll show you crazy!" *proceeds to slap himself in the face multiple times while wailing like Curly from The Three Stooges, pokes the drug dealer in the eyes, slaps the other drug dealers, and pulls out a gun.
  • Early Installment Weirdness: The first movie, before the series embraced its comedic elements, is much darker, with moody sax music, and a bit of a Film Noir vibe.
  • Ending Fatigue: The first movie has a minor case of this with the fight against Mr. Joshua. It's a cool sequence, but the plot's already been wrapped up.
  • Ensemble Darkhorse: Leo Getz (in the second film, at least).
    • The fourth film introduced American audiences to Jet Li, and his character is largely what makes that film watchable. Many American moviegoers left the theaters saying, "Who the Hell was that?"
  • Evil Is Cool: Mr. Joshua and Wah Sing Ku.
  • Even Better Sequel: Donner, Gibson, and Glover all consider the second one to be this.
  • "Funny Aneurysm" Moment: Riggs mocks Rudd's racism and calls him "Aryan" in the second film. Cut to 2006, and Mel Gibson is in hot water for making several racist remarks during his arrest. Cut to 2010, and he's in even more hot water for making even more racist statements during an argument with his girlfriend.
  • Hilarious in Hindsight:
  • Ho Yay: Riggs and Murtaugh are just loaded with this.
  • Memetic Mutation: Danny Glover has always been, and will always be, getting too old for this shit.
  • One-Scene Wonder: The Nigh Invulnerable pyro guy in 4's intro.
  • Rooting for the Empire: Just try not to cheer for Jet Li in the fourth film.
  • Sequelitis: A not too drastic example, but most noticeable with part 4.
  • Values Dissonance: On two separate occasions in the first film, Riggs demonstrates extreme homophobia. Perhaps fair for its time in 1987; stands out quite a bit in 2011.
  • Villain Sue: Jet Li's character descends into this with some of his more outlandish feats, in Mexican Standoff, he takes dismantles Riggs' gun with 'one deft move', and in another, he easily kills a man by grabbing his neck.
    • Backfires on him when he performs an impossible Bullet Dodge...And the round hits his brother instead, killing him.
