* AlternativeCharacterInterpretation:
** Did Toshio only mean to menace Rose by "playing" with her, or was he making a genuine attempt at friendship?
** Did Kayako specifically let [[spoiler:Allison]] live for so long so that the curse could spread to America?
* SugarWiki/AwesomeMusic: Every movie's score, especially the score of the second movie.
* FridgeLogic / PlotHole: Where on Earth did Naoko get hold of [[spoiler:Kayako's blood]] from? (Unless it's just a substance that represents it, or something.)
** Seeing how [[spoiler: Kayako]] is covered in blood, it's only a matter of getting close enough without being killed.
** Or... [[MundaneSolution maybe it's her own? She's her sister, after all. They share the same blood.]]
* IAmNotShazam: There is a surprising amount of people who apparently don't know Kayako's name and instead refer to her as "The Grudge" or "The Grudge Girl".
* ItsTheSameNowItSucks: Aubrey's plotline in ''The Grudge 2'' is often accused of this.
** This may also be the reason why the death of [[spoiler:Mrs. Davies]] was cut from the second movie - although pretty shocking in nature, it is visually a little too similar to the death of [[spoiler:Yoko]] from the first movie.
* [[HoYay Les Yay]]: There seems to be some very subtext-y moments between Allison and Vanessa in the second movie.
** The way Kayako seems to be all over her (usually female) victims when she kills them ([[spoiler:Karen]] and [[spoiler:Dr. Sullivan]], for example - the way she [[spoiler:clings to Karen's corpse]] after she kills her). A little bit of FoeYay, perhaps?
** Kayako/Susan is even [[LampshadeHanging joked about in the cast commentary for the first movie]], during the scene where [[spoiler:Kayako appears in Susan's bed]].
* {{Misblamed}}: Some detractors of the first film dismissed the [[spoiler:jawless Yoko]] scene as being an example of Americans [[BloodierAndGorier making the movie gorier]] than the Japanese version just for the sake of it... [[OlderThanTheyThink apparently unaware]] that the scene is a recreation of a scene from ''[[Film/JuOn Ju-on: The Curse]]'' in which the same thing happens to [[spoiler:Kanna]].
* {{Moe}}: Kayako herself - albeit before her death. (Most obviously in a certain deleted scene from the first movie.) She's still cute after her death, although [[CuteMonsterGirl in a rather different and disturbing sort of way]].
* {{Narm}}: Face it, the bickering couple scene in ''The Grudge 2'' is just ''funny''. Even the murder.
** The creepiness of Lisa seeing Toshio for the first time in ''The Grudge 3'' is [[NightmareRetardant somewhat lessened]] by the fact that Shimba Tsuchiya is clearly too old and too tall to be playing Toshio, who was only eight years old at the time of his death.
* NauseaFuel: The "milk" scene from the second movie: Lacey's friend Sally, having apparently been possessed by Toshio's cat, mindlessly drinks about half a large bottle of milk, before vomiting it right back into the bottle... and proceeding to drink it again.
* ParanoiaFuel: Kayako and Toshio can appear from and emerge from ''anywhere''.
* {{Sequelitis}}: ''The Grudge 3'' was not very well-received for several reasons: TakashiShimizu not being the director (although he did act as an executive producer), at least one possible plot hole, the BloodierAndGorier nature, lacking the AnachronicOrder of the previous titles in favour of a more linear narrative, [[TheOtherDarrin Aiko Horiuchi replacing]] Creator/TakakoFuji as Kayako, and Shimba Tsuchiya being clearly too old to play the eight-year-old Toshio. It isn't lacking in genuine scares, however, and it does have its supporters.
* SignatureScene: From the first movie: the shower scene; the climactic scene with Kayako crawling down the stairs (carrying on the tradition from the Japanese films); the scene where Susan is claimed by Kayako in her bed; and the scene where Alex is menaced by a [[spoiler: jawless]] Yoko.
* {{Squick}}: The deaths of [[spoiler:Yoko]], [[spoiler:Gretchen]] and [[spoiler:Naoko]].
* [[SurprisinglyImprovedSequel Surprisingly Improved Remake]]: Many feel the US remake of the third Japanese film is better. Considering the same director had a second shot at the story, he probably found ways to improve it.
* ToughActToFollow: Although Aiko Horiuchi's performance as Kayako is legitimately creepy and unsettling, she had the dubious honour of taking over the role from Takako Fuji, who had played the role from the very beginning of the ''Ju-on'' franchise and was considered iconic in the role.
* UncannyValley: Kayako is given an appropriately creepy walk via a combination of stop-motion effects and Creator/TakakoFuji and Aiko Horichi's talents at performing creepy, jerky movements. She also has an expressionless face - you can't detect any emotion from her (even though she's supposed to be the embodiment of UnstoppableRage.)
** Also, in the third movie, [[spoiler:Naoko]] has an incredibly unsettling walk after her transformation into StringyHairedGhostGirl, thanks to [[spoiler:her knee being broken]] prior to her death.
* TheWoobie: A good chunk of characters, but especially Allison, Jake, Aubrey and Rose.
