''Visitor Q'' is a [[BlackComedy very darkly comic]] and highly controversial Japanese V-Cinema film created by auteur Creator/TakashiMiike. The movie starts with a documentary filmmaker having sex with his teenage prostitute daughter. On his way home, he's attacked by a seemingly random stranger who knocks him senseless with a large rock, before delivering him to his house. The stranger immediately begins with the man's DysfunctionalFamily -- which includes his prostitute daughter, prostitute junkie wife, and abusive son. All the while, the visitor is videotaping him and his family. And that's just the start of the film. It is infamous for its rather disturbing scenes of odd fetishes and violence; and was included on a list of the top 25 most mind-bending movies in the June 2010 issue of ''FILM'' magazine.

!! This film provides examples of the following tropes:

* AttemptedRape: The father tries to rape his colleague but she dies of [[CrossesTheLineTwice his strangling]] before he can get it in. That's not keeping him from [[ILoveTheDead trying again]] though.
* AuthorAppeal: Lactation, which shows up in many of Miike's V-Cinema releases.
* BlackComedy: Rape, violence, incest, drug addiction, and necrophilia are all on display and PlayedForLaughs.
* BlackComedyRape: The father gave a man-on-the-street interview to a local gang and ended up getting a microphone shoved in a very uncomfortable spot while they filmed it. His co-workers are horrified (especially since he went on to broadcast the footage anyway) and ask him to take some time off from work. This is played for very DarkHumor.
* TheBladeAlwaysLandsPointyEndIn: In the third act, the mother throws a knife at her son and it lands pointy end in on a floor board. A minute later she throws a screwdriver at one of her son's bullies and it penetrates his forehead pointy end in.
* DomesticAbuse: How the son mistreats his mother.
* DysfunctionJunction: The entire family is practically on the brink of madness.
* ILoveTheDead: In the climax, the father kills a young female colleague, then strips her body naked and has sex with her corpse.
* GainaxEnding: The entire movie is surreal and hard to explain but the final scene involves [[spoiler: the mother showering the father and daughter with breast milk, then feeding the family]].
* {{Gorn}}: The family fights back against the local gang and kill them pretty brutally. The climax involves the father also going on a killing spree in and around a girl's high school.
* NoDeadBodyPoops: Almost all of the girls who are killed by the father avert this, as many of the girls are seen wetting themselves as they die, with their urine soaking through their panties and pooling on the ground around their bodies. Several of the girls' corpses are also shown with lumps of semi-solid brown substance oozing out of and staining their panties as they defecate in death.
* ParentalIncest: The father pays his daughter for sex.
* PunkInTheTrunk: The father moves the bodies of the dead school boys into the trunk of his car.
* TraumaCongaLine: The entire family. The son gets bullied and comes home to a crazy family everyday and even then, they still pop up to throw fireworks at their house. The dad is not respected at work, gets beaten and raped by a gang, pays his disrespectful daughter for sex, then ends up going crazy and has a few more problems once he turns to necrophilia. The mother has an unloving husband, horrible kids, a drug habit, and ends up in prostitution.
* VillainProtagonist: Take your pick, The father who's a murderer, rapist and necrophiliac? The daughter who's a disrespectful brat who encourages her dad to have sex with her? Or the son who's a domestic abuser to his mom? The only family member that is the least unstable is the Mother, and even then, she has her own problems with drug addiction. Even the Vistor who's there to teach the family the errors of their ways ends up doing a lot of morally questionable things in order to do so.
