* {{Anvilicious}}: ''Le temps détruit tout.''
* BrokenBase: Understandably, the film has received both high praise and harsh criticism. It was both booed and given a standing ovation at Cannes.
* CompleteMonster: Le Tenia is a twisted and sadistic pimp who assaults the main character Alex in an underpass at night after she tells him to stop beating up his whore, leading to [[RapeIsASpecialKindOfEvil a horrifying, prolonged and uninterrupted rape scene that lasts for]] '''nine minutes''', after which Le Tenia expresses his satisfaction by kicking Alex in the head repeatedly. As a result, she goes into a coma; made even more gut wrenching upon the reveal she was pregnant. Marcus and Pierre track Le Tenia to the Rectum nightclub, where Marcus gets into a fight with [[spoiler: a guy they believe is Le Tenia. When Marcus looks like his arm is going to get broken by this guy, Pierre rescues him by savagely beating in the other guy's head in so hard that [[{{Squick}} his skull is crushed]]. Meanwhile, the real Le Tenia looks on, faintly amused by it all, indicating he gets a kick out of violence.]]
* HarsherInHindsight:
** Something revealed towards the very end -- [[spoiler: namely that Alex was pregnant]], makes the events shown at the beginning of the film seem even worse.
** After the rape, the movie becomes increasingly lighter and happier, which makes the contrast with the disturbing start of the movie even nastier. In particular, the main characters have a slightly kinky sex scene near the end of the movie that's completely cringe-inducing, knowing how their day ends.
* MoralEventHorizon:
** Marcus' initial fight with the suspected rapist, and then Pierre's extinguisher bludgeoning of his face.
** La Tenia when he rapes and beats Alex.
* NauseaFuel: This film makes few allowances for those that suffer from motion sickness. The vertiginous camerawork and garish red lighting combined with the intense droning soundtrack caused a few people to vomit at the premiere. Low-frequency sound was also used in order to disorientate the audience.
* NightmareFuel: The rape scene. ''Nine minutes'' of horrifying, uninterrupted, and graphic rape. Holy shit.
** Let's not forget the fire extinguisher scene as well.

* SomeAnvilsNeedToBeDropped: RoaringRampageOfRevenge movies are pretty common, and it's rare to show what that'd actually be like in real life.

* UnfortunateImplications: The movie has come under fire for having potential homophobic and misogynistic implications [[http://www.slate.com/articles/arts/movies/2003/03/irreversible_errors.html in this article]].
