[[caption-width-right:350:Those cantankerous Kangs got hit by TheEighties [[EightiesHair worst]] [[DarkerAndEdgier of all!]]]]
->'''Maddy:''' No cause for panic? Two of my next-door neighbours have just disappeared down the waste disposal chute!

The Doctor and Mel decide to go and visit a famous housing project (because it has a nice pool), but it turns out that all of the fit adults left years before to fight a war. The block has devolved into a bizarre sort of anarchy, inhabited by color-themed all-female youth gangs called "Kangs" who use crazy terminology, rampaging janitor robots, cannibalistic old women, rule-obsessed security guys led by a guy who looks suspiciously like UsefulNotes/AdolfHitler, a lone quixotic draft-dodger, and the disembodied mind of the block's AxCrazy architect.

!!Tropes

* AffablyEvil: Tilda and Tabby are so courteous and welcoming to passers-by, until they break out a knife to butcher the guest with, [[ImAHumanitarian and then dinner's on to cook]]. It's a creepy affability, however.
* AfterTheEnd: Implied; the inhabitants of Paradise Towers refer to some kind of massive war happening which forced them to take refuge in Paradise Towers, and it's pretty clear that they've been forgotten about and abandoned by the outside world.
* TheApunkalypse: the Kangs are a G-rated version
* AxCrazy: Kroagnon
* BadBoss: The Chief Caretaker secretly arranges for some of his own men to be fed to his 'pet' in the basement. [[spoiler: And that's ''before'' he's possessed by Kroagnon and starts wiping them all out.]]
* BadassBandolier: Pex wears one. [[IJustWantToBeBadass It doesn't help]].
* BigDamnHeroes: Subverted by Pex, who has a habit of showing up and trying to save the day (usually with a fair bit of property damage involved) even when there's no danger whatsoever. He successfully manages to pull the trope off later in the story, just in time to save Mel from Tilda.
* BlandNameProduct: Fizzade
* BookEnds: The Doctor begins and ends the serial politely doffing his hat to what appears to be some kind of disused water pipe.
-->'''Melanie:''' No, Doctor.\\
'''The Doctor:''' Well, you never can tell.
* BotheringByTheBook / TalkingYourWayOut: How the Doctor escapes from the Caretakers
* BreakingSpeech: The Doctor gives one in the Regulation 13 Appendix 2 Final Conversation with the Chief Caretaker.
* ColorCodedForYourConvenience: the Kangs. (The colors are those of the three main British political parties.)
** Possibly a subversion, given that, although they are certainly color coded, there is no actual difference between the three groups of Kangs.
* DawsonCasting: the Kangs are definitely meant to be younger than the actresses playing them.
* EnemyMine: All the warring factions have to pull together against the threat of Kroagnon.
* EvilOldFolks: Tilda and Tabby, certainly. It is suggested that not all the Rezzies are quite as bad, however:
-->'''Maddy:''' ''[When the Kangs object to an alliance]'' I know that we residents have not always been as neighbourly as we might have been, but some have been worse than others. And the worst have gone... down the waste disposal chute.
* FanService: Averted -- despite eventually getting her swim, we never see Mel below her shoulders while she's in the pool.
* FutureSlang
* GrandTheftMe: Kroagnon on the Chief Caretaker
* GreatOffscreenWar: The backstory of Paradise Towers suggests that the current occupants are refugees from a massive war, mainly the elderly and the children, who were housed in Paradise Towers as a refuge while the able-bodied were sent off to fight, and the Caretakers are the maintenance / security team based there to take care of things until the war ended. It's heavily implied that they've been completely forgotten about by the outside world over the years.
* HeelFaceTurn: The Deputy Chief Caretaker and the surviving Rezzies [[EnemyMine throw their lot in]] with the Doctor and the Kangs when Kroagnon shows up and starts killing everyone. The ending suggests that everyone's going to try and work together from now on.
* {{Hypocrite}}: The Deputy Chief Caretaker is clearly not as familiar with the rules as he should or claims to be.
* ImAHumanitarian: Tilda and Tabby lure in the unsuspecting for this purpose.
* LargeHam: the Chief Caretaker, especially after Kroagnon possesses him.
** Richard Briers was a fine actor, but his performance in this story has been described as a 'career-low'. According to the OtherWiki, an article in the ''Radio Times'' [[http://en.wikipedia.org/wiki/Paradise_Towers pulled no punches]] on the matter.
* LawfulStupid: the Caretakers
* LockingMacGyverInTheStoreCupboard: the people who imprisoned Kroagnon in the basement apparently with all he needed to take control of the Cleaners and possess a new body
* LostTechnology: A downplayed example; one of the ways the Doctor gets the Red Kangs on his side is by showing them how to use a soft drink vending machine that's been in their base of operations all the time without them realising what it is or what it can do.
* MadArtist: Kroagnon
* MalevolentArchitecture: Kroagnon was on the point of turning Paradise Towers into this when his clients caught him at it and imprisoned him. His previous project Miracle City did end up like this. [[StealthPun It was a miracle anyone got out alive.]]
* MilesGloriosus: Pex
* MistakenForSpecialGuest: the Doctor is initially mistaken for the Great Architect
* MoodWhiplash: The Chief Caretaker initially hails the Doctor, believing him to be the Great Architect, with an awed, admiring speech about how the Great Architect will fix the place up, SetRightWhatOnceWentWrong and generally make everything better for everyone. Then:
-->'''Deputy Chief Caretaker:''' So what do we do with him now then, Chief?\\
'''Chief Caretaker:''' Kill him.
* MyRuleFuIsStrongerThanYours: How the Doctor escapes the Caretakers.
* [[NeverSpeakIllOfTheDead Never Speak Ill Of The Unalive]]: The Kangs.
* OminousMultipleScreens: The Caretakers headquarters has one of these.
* PaperThinDisguise: the Chief Caretaker, in an unfortunate real-life example. According to the Radio Times:
--> "there’s no escaping the fact that the Chief Caretaker, the key baddie in Paradise Towers, is just Richard Briers in a silly cap, silly moustache, putting on a silly voice."
* PercussiveMaintenance: Pex gets the elevator working again by simply kicking it.
* PsychoLesbian: According to WordOfGod (and the novelization), both Tabby and Tilda.
* PunchClockVillain: Apart from the Chief, the Caretakers are pretty much just the building's maintenance / security force who, with the devolving of Paradise Towers into chaos, have gone a bit weird and over-fixated on their rulebooks.
* PuttingOnTheReich: the Caretakers, and especially [[UsefulNotes/AdolfHitler the Chief]]
* RedemptionEqualsDeath: Pex
* ScrewThisImOuttaHere: Upon being confronted with the Kroagnon-possessed Chief Caretaker and his ranting about how the corridors of Paradise Towers are polluted with 'living flesh', it takes the Deputy Chief Caretaker less than a minute to decide that it'd probably be a better idea to run away and throw his lot in with the Doctor.
* SealedEvilInACan: Kroagnon was stripped of his body and imprisoned in the basement by the former residents of Paradise Towers after they discovered he was planning to turn the entire building into a DeathTrap for the residents.
* ShoutOut:
** The idea of a massive housing project being so ill-designed that it turns its residents into warring tribes had previously appeared in the J.G. Ballard novel ''High Rise''.
** '''Kroa'''gnon seems suspiciously like a semi-anagramatic villainous parody of Howard R'''oark'''e from ''Literature/TheFountainhead''.
* SuspiciouslySpecificDenial
-->'''Chief Caretaker:''' Careless chat about the robotic self-activating Mechapodic Mark 7Z Cleaners having got out of control is not going to help anyone! And may needlessly upset other Caretakers.
* StrangeSalute: the Kang's elaborate "how do you do" ritual, which looks like a ShoutOut to the video to Adam and the Ants' "Prince Charming". And the Caretakers' salute, which is the British playground "put your finger under your nose like a moustache to allude to Adolf Hitler" gesture.
* TeenageWasteland
* TooDumbToLive: You would think that, having battled through a dilapidated tower block crawling with murderous cannibals, fascistic caretakers, teenage street-gangs, mechanised death robots and something malevolent lurking in the basement, Mel might be a ''tad'' more reluctant to get into her bathers and go for a swim in the Paradise Towers swimming pool without being a little more suspicious that there might be something nasty lurking in there as well. True enough, she gets attacked by a cleaning robot.
