* AlternativeCharacterInterpretation:
** Some readers dislike Augustus, claiming that his grandiose mannerisms and his love of metaphor make him grating and pretentious, but others argue that he was meant to be written that way, because ''wanting'' to be impressive and memorable is an established character trait of his.\\\
There's also the interpretation that he's mainly interested in getting Hazel into bed. He's a teenaged boy knowing he might die ([[spoiler:and for the majority of his time with Hazel ''knows'' he's going to die]]) and he's only pursued girls he knows were dying, suggesting to some that he's not interested in a relationship (and that he perhaps hopes they will be easier to get into bed since they know they won't get too many opportunities to try it). This interpretation seems common among readers who found his courting of Hazel shallow and the relationship itself lacking in depth and being mostly about two hormonal teenagers finding each other attractive. Also there's his comment to Hazel that he hopes bringing her to Amsterdam might get him laid, which some interpret as not actually being in jest. [[spoiler:As to why he doesn't dump her once they've done the deed, it can be argued that as his illness progresses he wants to keep her close because she offers him comfort, or that he hopes he will get to sleep with her again.]]
** Some readers also dislike Hazel, feeling that she holds herself to be better than everyone else, is very judgmental, puts down other people's emotions instead of showing empathy and that she is extremely self-entitled. The way she tells Gus to be appreciative of the life and people around him rubs these readers the wrong way, as it comes across to them as her invalidating his (perfectly understandable) desire to have a larger life than what he got. On the other hand, Hazel does have a right to be a little offended since Gus is implying he doesn't feel their relationship is important.
** There are also readers who think Van Houten's behavior is pretty sensible to a ReclusiveArtist whose privacy has been disturbed, especially since his experience makes him unlikely to extend politeness to Hazel and Gus just because they're used to Cancer Perks. On the other hand, he ''had'' all but promised to see them, and Hazel and Gus had no way of knowing that, and he was still inexcusably mean and insensitive.
** Monica's mother going back inside to allow Hazel, Gus and Isaac to egg Monica's car. Does she just not want to argue with the teens who have eggs? Does she give them a pass because they have cancer? Or does she also think what her daughter did was a dick move and feels this is a worthy comeuppance for her?
** Monica herself as to whether she should be sympathised with or not. On the one hand, she's just a teenager who had a panic that was at least understandable. On the other, it was insensitive of her to make a promise she didn't end up keeping. Everyone else doesn't really get mad until after Isaac's surgery when she hasn't even contacted him at all - which is what prompts Augustus to egg her car. It's hinted that even the girl's own mother is disgusted with her.
* AwardSnub:
** The movie was not nominated for any Kids' Choice Awards. Since it is thought to have been the only movie with any chance of beating ''Film/TheHungerGamesMockingjayPart1'' its snub is especially significant. The book got nominated, but ultimately lost to ''Literature/DiaryOfAWimpyKid'' in one of its trademark upsets.
** Fox tried to get nominations for Best Adapted Screenplay and Best Actress for Creator/ShaileneWoodley. Neither were successful.
* SugarWiki/AwesomeMusic: The film's soundtrack is very well-chosen. "Boom Clap" is an incredibly catchy and upbeat EarWorm, while "Not About Angels" and "All of the Stars" are appropriately [[TearJerker tearjerky]] and emotional pieces for the film's third act.
* CrossoverShip: There are a number of fics where Augustus [[spoiler: finds a SecondLove in [[MundaneAfterlife the capital-S Something]] with [[Literature/LookingForAlaska Alaska Young]]]].
* EarWorm: "[[Music/CharliXCX BOOM CLAP THE SOUND OF MY HEART THE BEAT GOES ON AND ON AND...]]"
* FunnyAneurysmMoment: Hazel's "you could be an axe murderer" line becomes a lot grimmer after watching John Green's video about how he [[https://www.youtube.com/watch?t=196&v=wQKwwC72BJE went to high school with a soon-to-be axe murderer.]]
* HarsherInHindsight: Seeing Shailene Woodley having to [[spoiler:say goodbye to Ansel Elgort as he dies from cancer]] might become even sadder if both actors are cast in ''Film/TheDivergentSeriesAscendant'', where [[spoiler: Caleb (played by Elgort) will have to say goodbye to his sister (played by Woodley) before her lethal HeroicSacrifice]].
* HeartwarmingInHindsight: Lotte Verbeek giving the kids a tour of the Anne Frank House can make one smile if they've seen her in ''Series/AgentCarter'' where she plays a Holocaust survivor - who is also an IronWoobie like Hazel and Gus.
* HilariousInHindsight: Both this film and ''Film/{{Divergent}}'' were released around the same time as each other. Both based on {{young adult|Literature}} novels and both starring Creator/ShaileneWoodley and Creator/AnselElgort. Playing love interests here and brother and sister in ''Divergent''. What's more is that Shailene Woodley had been offered the title role in ''Film/{{Carrie|2013}}'', which also featured Ansel Elgort - where their characters would have been JustFriends.
* HoYay:
** Isaac points out Augustus’s “physical attractiveness” multiple times. Also, Augustus claims that his hot body caused Isaac’s blindness. And on the dubiously canonical Q&A blog that John Green runs (see main page for link), Isaac is referred to as both “gay” and “a [future] ballerina.” Both are said in jest, but still.
** Isaac accidentally grabs Augustus’ thigh. The first thing Augustus says to him is, “I’m taken.”
* HypeBacklash:
** After the [[https://www.youtube.com/watch?v=642lKXC97c4 clip]] for the “it’s a metaphor” scene was shown at the MTV Movie Awards, it received a surprising level of backlash, due to people seeing it as pretentious when said out loud by an actor. Plus, what he's describing isn't a metaphor, making him sound like a hipster who's just using random words he heard somewhere to sound smart (which, according to WordOfGod, is very intentional - Gus is a smart kid, but he uses a lot of words and concepts wrong, like any other teenager).
** Many people don't care to watch the movie or read the book because of its routine "cancer patient falls in love and dies tragically young" plot.
* IronWoobie: Augustus is this from the start of the novel. Despite having a prosthetic leg, he takes everything in stride and tries to make the best out of his situation. [[spoiler: He begins to crack by the end]].
* ItWasHisSled: [[spoiler: Gus dies.]]
* JerkassWoobie: Van Houten. Yes, he’s a drunk asshat, but you have to admit he is sort of a tragic character. [[spoiler: His daughter died of cancer, and he's been a depressed alcoholic ever since]].
* MemeticMutation:
** This book (not to mention the author) has a pretty big following on {{Tumblr}}, mainly for being a massive TearJerker and a major source of feels. A common RunningGag is for newtime readers to document their first readthrough of the book and the progressive regression into a blubbering puddle of tears.
** "Okay?" "Okay."
** “My X are Y that I cannot fathom into z.”
** “I X the way you X: slowly, then all at once.”
** “It’s a metaphor; you put the X in between the Y, but don’t give it the power to Z.”
** More of a meta example but [[http://fishingboatproceeds.tumblr.com/post/88201353990/faultinourstarsmovie-normal-sucks-i a comment that John Green made on his official Tumblr]] regarding a gifset of Hazel and Gus, which spawned a meme (largely from the book's critics) about John being the inventor of feminism.
-->'''John Green''': I just want to point out one thing here: When was the last time the girl kissed the boy in a teen romance? Ever? Has it happened ever? I seriously think it might not have happened ever.[[note]]This comment was met with immediate backlash, with people pointing out that this trope is much OlderThanTheyThink. John swiftly [[http://fishingboatproceeds.tumblr.com/post/88287487983/a-note-on-yesterdays-posts corrected himself]] afterwards, admitting that he got a little carried away with his euphoria over the film being released. In the book, it's not clear who kisses who first, and he was commending the filmmaker's decision to have Hazel kiss first rather than trying to self-promote.[[/note]]
** The beautiful X is beautiful.
** Purposefully confusing Augustus Waters with [[Literature/CharlieAndTheChocolateFactory a certain other Augustus]].
** "No...I just want to cry and play video games."
** Once the film was released, there were plenty of memes theorising that Augustus's name is really [[Film/{{Divergent}} Caleb Prior]] and Hazel is a ReplacementGoldfish for [[spoiler:his dead sister]].
* {{Narm}}:
** A common criticism about the dialogue, which is flowery and grandiose. Others like it for the same reasons.
** Their date in Amsterdam is very...romanticized, possibly owing to the author's own love for the city.
** When strangers yell "beautiful couple is beautiful" at the main characters. "[adjective] [noun] is [same adjective]" is an old {{meme|ticMutation}}.
** Some readers thought the throng of people applauding after Hazel and Augustus make out in the Anne Frank house was a bit much.
* ShipsThatPassInTheNight: A large amount of fics pair off [[PairTheSpares Gus and Hazel's respective best friends Isaac and Kaitlyn]], who never even meet in the book.
* SignatureSong: [[Music/CharliXCX "Boom Clap"]]
* ViewerGenderConfusion: From [[http://imgur.com/gallery/tf78fHT/ the poster]] for the film alone, many people couldn’t tell the gender of either person in the picture.
%% * TheWoobie: Both of the leads, plus Isaac and Hazel’s [[spoiler: and eventually Augustus’s]] parents.
