Harry Potter and The Goblet of Fire/YMMV


 * Abandon Shipping: . Despite this book launching their ship, it's torpedoed at the end when.
 * Artistic License Biology: In-universe example. In order to make Hagrid look bad to Rita Skeeter, Malfoy claims that in addition to being attacked by Buckbeak, Crabbe also got a bad bite off of a flobberworm. Which mainly eat lettuce, don't have any teeth, and have a X (boring) classification from the Ministry of Magic.
 * Complete Monster: Voldemort of course, along with Barty Crouch Jr. (although the latter was only portrayed as such in the film, as the book has him being more closer to a Woobie, Destroyer of Worlds). They also set the stage for other Complete Monsters to be introduced later on, namely Umbridge, Bellatrix, and Greyback.
 * Crowning Moment of Awesome: Several, though one of the many mentions goes to the ending, where Fred, George, Harry, Ron, and Hermione all jinx Malfoy, Crabbe, and Goyle with every spell they know.
 * Crowning Moment of Heartwarming: Hermione kissing Harry and Ron on the forehead after they came back from underwater in one piece.
 * Draco in Leather Pants: Barty Crouch, Jr. has his share of fangirls, as can probably be expected whenever one casts David Tennant as anything.
 * Hero Antagonist: Cedric is a mild example, as he was Harry's rival both in the tournament and in winning Cho's affections.
 * High Octane Nightmare Fuel: Rowling was apparently surprised that the editors didn't object to Voldemort's resurrection scene, specifically
 * Wormtail cutting off his own hand.
 * The trial  On a related note, the torture of Frank and Alice Longbottom.
 * For those with a fear of deep, dark water, the Second Task as a whole.
 * Hilarious in Hindsight: After the First Task, when Madam Pomfrey, the school nurse, is attending to the Champions' wounds, she exclaims, "Dragons! ...Last year dementors, this year dragons, what are they going to bring into this school next?" Of course, fans all know by now that the next year would see something far worse enter the grounds of Hogwarts School: Professor Umbridge as The Tyrant Taking The Helm.
 * The whole fact that Harry's incredibly handsome rival Hogwarts champion is played in the movie by future Edward Cullen. And really, the rivalry between Harry's supporters and Cedric's supporters could easily be compared to the Fandom Rivalry between Harry Potter and Twilight -- particularly the way in which Harry and Cedric (a.k.a. Daniel Radcliffe and Robert Pattinson) are nothing but civil to each other while each has fans who volatilely bash their hero's rival.
 * It doesn't help that Cedric first makes an appearance by jumping out of a tree. Maybe, he was bothered?
 * Also, David Tennant said in an interview at the movie premiere that he'd probably never be part of such a large fandom again. One year later...
 * Launcher of a Thousand Ships: Continuing the series tradition, the introduction of new characters as well as already existing ones being made prominent created some new ships, including Harry/Cho, Cedric/Cho, Harry/Fleur, Ron/Fleur, Hermione/Krum, Hermione/Cedric, Krum/Fleur, Cedric/Fleur.
 * Magnificent Bastard: Barty Crouch Jr.
 * Narm: In-universe, Harry thinks that Professor Moody must find the whole scenario where Harry is caught out of bed trying to figure out the second clue (an otherwise dramatic and intense moment) to be quite silly, since his eye is able to see Harry's awkwardly-positioned body through the Cloak.
 * No Such Thing as Bad Publicity: This entry brought the Moral Guardians out in full force against the series, ensuring this trope occured. While still a good book in its own right, it wouldn't have been nearly as successful without all the parents, politicians, and preachers decrying it for converting children to witchraft and Satanism. Some held burnings of it. Of course, this required them to buy copies to burn them.
 * Ship-to-Ship Combat: Also, continuing the series tradition, the supporters of the new and already established ships took all new offensives for their pairings.
