* {{Bowdlerisation}}: The book was ''way'' more sexual and openly homophobic than the movie was.
* BrokenBase: About [[spoiler:Chiba]] hooking up with [[spoiler:Tokita]] at the end. Some believe it is a proof of EarnYourHappyEnding for both characters, others see it as jarring male WishFulfillment, and others believe the movie would have gone better without any romantic pairings at all.
* CompleteMonster: [[spoiler: Seijiro Inui, better known as The Chairman]], was introduced as a stern man who disapproves of the Dream Machine project at first. However, it is revealed that he is behind all the bad things that happen. Stealing three Dream Machine prototypes, he used it to MindRape some innocent people, causing them to [[DrivenToMadness become insane and almost mortally wound themselves]]; and he also used the machine on [[spoiler:Tokita's assistant, Himuro]], to [[FrameUp frame him for the crimes that he committed]], and leaves him as nothing but an EmptyShell. When he and [[spoiler:his assistant, Osanai]], ended up being found out by [[TheProtagonist Atsuko Chiba]], [[spoiler:in her Paprika persona]], for their crimes, they pinned her to the table and, despite [[spoiler:Osanai's]] love for Chiba, [[spoiler:the Chairman]] demands to finish her off and tries to take control of [[spoiler:Osanai's]] own body. After [[spoiler:Osanai]] got murdered, [[spoiler:the Chairman]] then turned himself into a nightmarish form and then threatens to darken the world, and tries to [[RealityWarper rewrite reality itself to suit his own whims]]. Despite [[NotSoWellIntentionedExtremist claiming to be well-intentioned in his goals]], [[spoiler:the Chairman]] at the end of the day was a [[AGodAmI delusional madman with a god complex]], and once he ended up achieving his goals, the true monster he really is came out.
* CrowningMusicOfAwesome: The entire soundtrack, by Music/SusumuHirasawa, "Parade" and "Mediational Field" in particular.
** Special honors go to "[[http://www.youtube.com/watch?v=DMc2EW6Pmkk The Girl in Byakkoya]]" though. The crazy juxtaposition of acoustic and electronica make for a song that's memorable, enjoyable and strangely romantic.
* EarWorm:
** "Mediational Field", the opening theme, the ending arrangement, and "The Girl in Byakoya".
** ''[[http://www.youtube.com/watch?v=APIKVLw1tT0 Parade]]'' will instantly [[NightmareFuel invade your mind.]]
* FanNickname: Tokita = [[Creator/ValveSoftware Gabe Newell]]. They both have messy brown hair, wear polo shirts, love technology, and are BigFun.
* FanPreferredCouple: Some viewers have lots of trouble accepting [[spoiler: that Chiba loves Tokita, and would rather have had her [[RescueRomance end up with Konakawa.]] This ignores how the [[MisaimedFandom fake ending with Konakawa and Chiba kissing in the sunset is supposed to be making fun of trite, cliché movie endings, which implies that pairing them together would have made for a really, really bland and predictable ship.]]]] On the other hand, the aforementioned viewers would then argue that [[spoiler:Chiba ending up with Tokita is equally trite and cliché for its [[UglyGuyHotWife wish fulfillment]] for [[DoubleStandard male audiences.]]]]
* HarsherInHindsight: All the talk about Konakawa's incomplete film. ''Paprika'' was Satoshi Kon's last completed project; he died partway through making another film called, coincidentally enough, ''The Dream Machine''.
* HilariousInHindsight: See FanNickname.
* MemeticMutation: Thanks to WebOriginal/AMVHell, [[https://www.youtube.com/watch?v=hRTjtpkLGoA "I'M ON SHROOMS!"]]
* SignatureScene: The dream parade, which appears everywhere in advertising for the movie and was Creator/SatoshiKon's favorite scene to make.
* StrangledByTheRedString: [[spoiler: Chiba and Tokita.]] Yes, there are hints - subtle hints - of mutual interest, but let's face it, her words to him are frequently cutting and cruel, way beyond what BelligerentSexualTension allows.
* SubbingVsDubbing: A rare case where both sides have merits. The first meltdown dialogue comes off like a poorly translated metaphor in the subbed version, while the dubbed version makes it clear that the speaker's lost his mind. Interestingly, the dubbing goes for the spirit of the script rather than the translation, leading to entirely different but still effective dialogue.
* TearJerker: "But what about the rest of it?" Konakawa finally admits why movies are a TraumaButton for him, after having a few drinks; when he was younger, he and a friend worked on films. They in fact started working on a movie about two former friends who become bitter enemies. Then Konokawa, in his words, got cold feet and decided to enroll in the police force. His friend died before the movie was completed, and he regrets that they never finished it. Konokawa also fears that he's not honoring his friend's memory and his childhood dreams. [[spoiler:By the end of the movie, Paprika helps him realize that he didn't waste his life or his friend's ambitions by becoming a cop; he's living out the fantasy they created, becoming the hero they imagined, and honoring his friend's memory. The dream version of his friend admits it as much by encouraging him to do "the rest of it".]]
* TheyChangedItNowItSucks: Inverted: A lot of people who've read the book much prefer the movie.
* UglyCute: Tokita, who may be morbidly fat, but has an expressive, cute baby face. Then again, it dips into UncannyValley for some.
* VisualEffectsOfAwesome: Taking into account the lavishly detailed and flowing animation, (including many scenes with phonetically-animated lips,) meticulously painted backgrounds, and the wildly creative parade scenes (containing perhaps hundreds of different characters,) this is one gorgeous-looking film!
* TheWoobie: Tokita. An innocent scientist who couldn't comprehend that people would use his invention for evil, he created a machine that was meant to help others with their traumas. For his troubles he finds out someone he trusted stole the machine and is using it to drive people to nervous breakdowns, and Chiba yells at him for not considering the consequences. To atone for his lack of judgement, [[spoiler:he dives into the dream world and gets trapped trying to fix his mistakes. Then while in the middle of dream logic, he tries to eat the woman who loves him and can't recognize who he is anymore. Poor guy!]]
