YMMV / The Professional

  • Awesome Music: Sting's "Shape of My Heart", the end credits theme.
  • Complete Monster: Detective Norman Stansfield is a DEA Agent who takes advantage of his position to terrorize, extort and kill who he wants. On a drug bust, Stansfield decides to get high on drugs and, while playing classical music, slaughters the whole family, including the couple's baby son. His only emotion over it is how he'll explain the death to his superiors. Stansfield, when confronted by the couple's 12-year-old daughter later, think that she's there to kill him, but when she can't bring herself to and breaks down crying, Stansfield asks her if she enjoys living. When she says she does, Stansfield makes clear his intent to kill her, saying he takes no pleasure in taking the life of someone who doesn't value their own.
  • Crosses the Line Twice: Stansfield is so over-the-top with his violence, from pausing a massacre to lecture someone about classical music to shooting at an old lady for not going back into her apartment when told, his psychosis is often as amusing as it is horrifying.
  • Hilarious in Hindsight:
    • This wouldn't be the last time Gary Oldman plays a cop in a corrupt precinct in a city full of psychopaths. His character was just a wee bit different the next time around, though...
    • Stansfield constantly talking about how much he loves Beethoven was quite appropriate in that Gary Oldman starred as Beethoven in Immortal Beloved, which came out later the very same year.
  • Love to Hate: Norman Stansfield is a raging, psychotic, drug-addicted, Dirty Cop who will kill at the drop of a hat. However, thanks to Gary Oldman's incredible over-the-top and oftentimes funny performance, it's almost impossible not to love him as a villain.
  • Memetic Mutation: Everyone? EEEVVERYYYYOOONNEEEE!!!
  • Moral Event Horizon: Stansfield crosses it fairly early on, when he kills Matilda's family.
  • Narm:
    • Léon's slow-motion, cross-eyed roar, seemingly apropos of nothing, right before his room gets hit with a grenade.
    • Oldman's performance of Stansfield can occasionally slip into this, depending on who you ask.
  • Nightmare Fuel: Norman Stansfield: A drug-addicted psycho with the law on his side.
  • Retroactive Recognition: Adam Busch, best known as Warren Mears from Buffy the Vampire Slayer, has a bit part in the film.
  • Special Effects Failure: Stansfield discovers the grenades in Leon's vest. Cut to outside, where one of the cars blows up before the explosion happens in the building itself.
  • Tear Jerker: Léon's death. A rewatch of the movie (and a reminder of his status as The Woobie) only makes it worse.
  • "Weird Al" Effect: Those who are not familiar with this film will believe that the "Get me everyone!" line originated in the 2005 video game Need for Speed: Most Wanted.
  • The Woobie: The main characters. Léon especially, who even as a hired killer, behaves rather childishly and innocent. He drinks milk, waters potted plants and watches old musicals with the look of a fascinated boy.
