!!The novel contains tropes of:
* TearJerker: [[spoiler: In a week the dog was dead.]]

!! The 2007 Film:
* HilariousInHindsight: [[https://www.youtube.com/watch?v=1tGXEATdxIc A billboard]] found in the background of a scene promised that a ''ComicBook/{{Batman}}'' and ''ComicBook/{{Superman}}'' crossover movie was in production JustBeforeTheEnd. 6 years after the release of the movie, [[Film/BatmanVSupermanDawnOfJustice it was officially announced]].
* MemeticMutation: GODDAMNIT, [[BeamMeUpScotty FRANK]] and WOLL SMOTH, which spun into an entirely unrelated meme.
* NightmareFuel: Neville going into a darkened building, a likely place to find lots of Infected, to search for his dog. He's so obviously terrified you can't help but be frightened with him.
** The zombies look very frightening.
* OneSceneWonder: She has about 1 minute and a half of screen time at the beginning of the film (and isn't listed in the credits), but Creator/EmmaThompson as Alice Krippin is so delightful you desperately want to know more about the woman who inadvertently created TheVirus.
* SpecialEffectsFailure[=/=]UncannyValley: The zombie/vamps are pretty obvious CG.
** WordOfGod said that they were trying to use extras at first, but since it required constant hiperventilation, they were forced to use CG instead.
* TearJerker: The aforementioned [[spoiler: Shoot The Dog moment]], and the moment Dr. Neville begs [[spoiler: the mannequin]] to say hello to him. Though some found the latter Narmy. Also the "Look Daddy, a butterfly," line right before [[spoiler: Dr. Neville's demise and the death itself]]. Finally the infected mother begging for her daughter to be taken to safety.
* TheyWastedAPerfectlyGoodPlot: The film's alternate ending comes closer to the message of the novel than the ending that made it into the movie and fills the above-mentioned plot hole, in addition to many others. It did poorly with test audiences, though, so ExecutiveMeddling changed it to an ending that is completely different and misses the point of the entire novel, twisting the message so that it can still fit the title, but in almost the exact opposite way that the original ending fit it.
* TheUntwist: At least in the cinematic version.
