History YMMV / ThirteenGoingOnThirty

* TearJerker:
** Jenna breaking down over the big grown up world of hurt to Music/BillyJoel's "Vienna."
** Jenna gradually finding out [[spoiler:what a {{Jerkass}} she's been as an adult]].
** Poise shutting down in the end. Especially when things were just beginning to get better for them, right before Lucy decides to be petty, and [[MoralEventHorizon sell out Jenna's redesign pitch out of jealousy—therefore finishing what Jenna had originally started, and putting all the employees at Poise unemployed.]]
** What Matty went through in the original timeline: He and Jenna were next-door neighbors who probably knew each other from toddlerhood and became seemingly inseparable best friends. Then one day, Jenna decides to become a "Six Chick" and not only abandons Matty from then on, but possibly mocks and bullies him at times. This gets bad considering he had feelings for her when that happened. In a single moment, what was once an absolutely beautiful friendship, turned into something that left a gaping hole in Matty's heart that wasn't filled for years. He did of course move on as an adult and ended up doing fairly well for himself, but that must've been a pretty emotionally traumatic thing for a 13-year-old to endure.
** Jenna confessing her love to Matt [[spoiler: right before his wedding to Wendy. He admits that he's loved getting to reconnect with her, but they can't just ignore the last 17 years and he's moved on. Jenna tearfully accepts it, and is given the dream house Matt had made for her 13th birthday. Before she leaves, trying to hold back tears, Matt says that he always loved her]].
** And after that, Jenna tearfully looks at the house as the wedding music starts playing behind her.

* ProtagonistCenteredMorality: Though he does go through with the wedding (and this is ostensibly supposed to be the honorable choice), Matt treats Wendy ''terribly'' and shows her a boggling amount of disrespect over the course of the film. Jenna only finds out that Wendy exists in the first place when Jenna and Lucy bump into Matt while he's out shopping with her, Matt is obviously distracted and thinking about Jenna when Wendy flies into town to see him and ignores her over the lunch she bought him, Matt makes plans to hang out with Jenna ''the night before his wedding'' without even telling her that it's the night before his wedding, and he ''kisses Jenna'' and considers leaving Wendy for her, all presumably without telling Wendy that any of this happened.

* TheyWastedAPerfectlyGoodPlot: Some critics noted how the film missed an opportunity to have Jenna become a FishOutOfWater in regards to then-current technology (with the only reference to it being a RunningGag with Jenna thinking she's hearing noises in her head when cellphones are going off)and also in regards to how much pop culture had changed since the 80s.

** Certainly for Marvel comics fans due to the fact that this movie includes [[Film/{{Daredevil}} Elektra Natchios]] as Jenna Rink, [[Film/TheAvengers2012 Dr. Bruce Banner/The Incredible Hulk]] as adult Matt, [[VideoGame/UltimateSpiderMan Spider-Man]] as teenaged Matt, [[Film/AvengersAgeOfUltron Ulysses Klaue]] as Richard, [[Film/AntMan1 Maggie Lang]] as Lucy "Tom-Tom" Wyman, [[Film/XMenOriginsWolverine Kayla Silverfox]] as Wendy, and [[Film/CaptainMarvel2019 Carol Danvers/Captain Marvel]] as one of the Six Chicks.

* HarsherInHindsight: Adult Jenna's flirtation with a child is cast in a harsher light not only by the cultural shift of the metoo movement, but by her adulation of Franchise/MichaelJackson, who would have a fresh PaedoHunt scandal break out between the production of this movie and its release.

** Poise shutting down in the end. Especially when things were just beginning to get better for them, right before Lucy decides to be petty, and [[MoralEventHorizon sell out Jenna's redesign pitch out of jealousy- therefore finishing what Jenna had originally started, and putting all the employees at Poise unemployed.]]

* AlternateCharacterInterpretation: Lucy is meant to be a straight up antagonist, but it's possible to read her as a former AlphaBitch who grew up and matured somewhat - she sincerely enjoys herself doing the Thriller dance, seems to like Jenna as a friend and appears genuinely hurt [[spoiler: when she discovers that Jenna essentially screwed her over]]. It's possible to read her [[spoiler: FaceHeelTurn in the third act as a little more understandable]].

* JerkassWoobie: Jenna herself, though the Jerkass part is only technical. She realises just what an awful person she grew up to be and can't handle it. Jennifer Garner is very good at looking like a kicked puppy when the scene calls for it.
* SugarWiki/MomentOfAwesome: The "Thriller" choreography (yeah, the one from Music/MichaelJackson) is freaking awesome.

** Due to a FreezeFrameBonus, you can see that Brie Larson's character in the Six Chicks was replaced by Jenna after she became popular. It would later be the other way round, with Jennifer Garner first playing Elektra and then getting replaced once the Franchise/MarvelCinematicUniverse started up.

** Felicity Jones can be seen on the covers of the magazines at Poise and Sparkle.

** Brie Larson as one of the "Six Chicks" during her child actor phase.
** Ashley Benson as one of the "Six Chicks" in the opening.

* ValuesDissonance: Even if she was being friendly, the scene where Jenna is having a sleepover with her teenage neighbor and the girl's friends wouldn't go over well these days.
** Jenna wears hair chopsticks as a fashion accessory, though popular in the early half of the [[TurnOfTheMillennium 2000s]], would be considered cultural appropriation in recent years seeing as chopsticks are used as eating utensils in East Asian cultures.
* ValuesResonance: Jenna flirting with a teenage boy is PlayedForLaughs but it gets a {{Squick}} reaction from Lucy, who asks if Jenna wants a jail sentence.

* HilariousInHindsight: Certainly for Marvel comics fans due to the fact that this movie includes [[Film/{{Daredevil}} Elektra]] as Jenna Rink, [[Film/TheAvengers2012 Dr. Bruce Banner/The Incredible Hulk]] as adult Matt, [[VideoGame/UltimateSpiderMan Spider-Man]] as teenaged Matt, [[Film/AvengersAgeOfUltron Ulysses Klaue]] as Richard, [[Film/AntMan1 Maggie Lang]] as Lucy "Tom-Tom" Wyman, and [[Film/CaptainMarvel2019 Carol Danvers/Captain Marvel]] as one of the Six Chicks.
