History YMMV / AllGrownUp

** Phil, Lil and Kimi in "All Broke Up". When Tommy and Rachel have to separate, due to Rachel moving away, they don't believe Tommy when he insists he's not as heartbroken as they think he is. They resort to completely smothering him, refusing to even listen to him. Sure Tommy's eventual act was a bit out of line, but it's somewhat understandable considering how overbearing they were. Blowing their allowance and "pulled an all nighter" for their surprise of Rachel coming back to town, which ends up enraging Rachel and humiliating Anita, seems like a fitting comeuppance. Chuckie did the same, but he realised his mistake at the end of the episode, and comforts Tommy.

** With Tommy becoming an amatuer filmmaker, Phil and Lil would've been perfect people to work with if he ever did a horror movie or anything else with gross special effects. They do actually touch on this in "Interview With A Campfire", where Lil is the main actress in Tommy's ''{{Film/Scream 1996}}'' {{Expy}}.

** Everyone is obsessed with a ''Anime/YuGiOh'' {{Expy}} around the time it was huge in pop culture.

* TearJerker:
** From the second episode where Lil moves out of her and Phil's room into one of her own. Just the moment where Phil walks into the room to find her stuff gone and sadly looks at pictures of them together as kids, ending with a shot of them in the mud from ''Rugrats''.
** Tommy's fate in "All Broke Up." Rachel thinks he's been cheating and calls things off with him, the potential new girlfriend gets furious and thinks she's been set up, and of course most of Tommy's friends are furious that he lied to them. Thankfully, in spite of Tommy being nigh-inconsolable, Chuckie visits to try and help and stays there by the end of the episode.
** In one episode, Susie gets conned out of a thousand dollars by a woman who told her that she would make her a star. When she tells Alisa (her sister), the latter frets about it and Susie assures her that she'll pay her back. Alisa's response is pretty sobering, especially considering that it's TruthInTelevision.
-->'''Alisa:''' (''[[AngerBornOfWorry understandably angry]]'') The money!? Susie, a ''lot'' worse could have happened to you than losing a thousand dollars! You go around with a woman you don't even know, say yes to whatever she tells you to do...she could have taken it [[AdultFear a lot farther]] than she did! ''THINK ABOUT IT!''
** Speaking of AdultFear, remember Tommy's flashback to how he nearly drowned while on a fishing trip with his grandpa? Now imagine what ''Lou'' must have been thinking during the whole thing...

* VindicatedByHistory: The show was initially met with poor reviews online, but over time, it gained a huge cult following. In 2020, thanks to growing nostalgia for it, ''All Grown Up'' was subject to a video titled ''[[https://www.youtube.com/watch?v=cLp53Gg6u08 The Strange Rugrats Spin-off That Kind of Worked]]''. Especially in light of the poorly received ''Rugrats'' reboot making ''All Grown Up'' look better by comparison.
* WhatAnIdiot:
** What in the world made you think throwing a bowling ball through your roof was a ''good'' idea, Tommy?
** Drew and Stu basically say this to each other when they realise that the car they threw off of a cliff originally belonged to [[spoiler: Elvis.]]

* UnintentionallyUnsympathetic: Dil big time in "Oh Brother, Can Thou Spare The Time". The plot is about Dil feeling forgotten because Tommy wins an award and gets a lot of extra attention, and Tommy is the one who has to dramatically apologise for not making time for him and neglecting his brother. Except Tommy ''did'' make time for him, indulging in Dil's ridiculous bucket list over what looked like days. And one of the instances of him 'neglecting' Dil is because a mob of {{Loony Fan}}s were swarming him and dragging him off, the other being Tommy taking a phone call from a reporter. And then Dil is the one who goes on a PointAndLaughShow to claim that Tommy shut him out, making Tommy look far more like a {{Jerkass}} than he was. It looks instead as though Dil was expecting Tommy to spend every waking moment of his life with him, and his main problem was his own giant insecurities. And it was Tommy who had to coax that out of him. Dil basically acts like a self-centered {{Jerkass}} and expects to be forgiven because he couldn't handle having a brother that *gasp* other people wanted to talk to for a change.

** With Tommy becoming an amatuer filmmaker, Phil and Lil would've been perfect people to work with if he ever did a horror movie or anything else with gross special effects.

** Tommy's camcorder is likewise late '90s/early 2000s technology that still shoots on video tape, and the characters likewise watch his films on VHS.

* VindicatedByHistory: The show was initially met with poor reviews online, but over time, it gained a huge cult following.

* TheScrappy: Savannah. She's basically Angelica without any redeeming qualities and always does everything she can to make Angelica miserable.

* FanPreferredCouple:
** Kimi and Tommy (half of the images of them on [=DeviantArt=] are them getting married). Which is why many people consider TP+KF that TheyWastedAPerfectlyGoodPlot.
** Chuckie and Lil seem to be the second-most popular pairing among fans of the show, usually as the BetaCouple to Tommy and Kimi. This is despite them getting even less deliberate ShipTease than Kimi and Tommy had, which amounts to just one comment from Lil saying that she finds Chuckie rebelling “kind of attractive”. Although to the shippers’ credit, Lil and Chuckie were seen to have great chemistry as friends too.

** The Sulky Boys are also a parody of the 90s and 2000s {{Boy Band}}s that were starting to fall out of popularity.
** Tommy's camcorder is likewise late 90s/early 2000s technology that still shoots on video tape, and the characters likewise watch his films on VHS.

* AuthorsSavingThrow: Due to some FridgeHorror at how someone like Angelica could have turned out as an adult (RonTheDeathEater paints her ''Rugrats'' self as a complete sociopath), ''All Grown Up'' shows that she mellowed out a lot as she got older, while still keeping ''some'' characteristic {{Jerkass}} quirks.

* UnintentionalPeriodPiece: "It's Cupid, Stupid" is centered on a parody of Li'l Romeo (played by the man himself), a rapper from the early 2000's and star of the 2003 Nickelodeon sitcom ''[[Series/{{Romeo}} Romeo!]]''. He hasn't been very active since the 2000's, so very few people would recognize the parody today.

** Dil was viewed as the most annoying character on ''Rugrats'', due to being TheLoad who couldn't talk and essentially had no personality. Here in the spin-off he's given the personality of a CrazyAwesome CloudCuckooLander who usually gets the best lines. He's one of the favourite characters of ''All Grown Up''.

** Tommy's fate in "All Broke Up." Rachel thinks he's been cheating and calls things off with him, the potential new girlfriend gets furious and thinks she's been set up, and of course most of Tommy's friends are furious that he lied to them. Sure, Chuckie tries to cheer him up at the end, but even then Tommy's just too miserable.

* TheProblemWithLicensedGames: It may surprise a few that the series actually did get a couple of video games, one PC game based on the pilot (which suffers from FakeDifficulty), and one UsefulNotes/GameBoyAdvance title which was a dress-up game starring the girls. Neither was remarkable, and both fell off the radar as quickly as they came.

* ContestedSequel: Some fans disliked the show for its massive differences, considering several characters got massive personality changes from toddler to preteen. However there are plenty of fans that enjoyed this and ''Rugrats'' - and there is still fan art/fanfiction being created based on ''All Grown Up''.

* WereStillRelevantDammit: This show is meant to do this for the ''Rugrats'' franchise.

* UncannyValley: The character designs may not seem like this at first, but when you notice the little things such as huge heads resting on tiny necks, it makes you wonder how they even turn their heads without falling over.

* DesignatedMonkey: Tommy becomes this in his preteen years, whenever his friends make him the scapegoat of their fury, whenever they're in a tight situation. This is done episodes like "Truth or Consequences", "Dude, Where's My Horse?", "All Broke Up", and "Brothers Grimm".

* EpilepticTrees: People were trying to figure out if Savannah Shane and Samantha Shane were one and the same girl (they do [[OneSteveLimit share a last name,]] after all,) despite looking and acting completely different. It doesn't help that Klasky-Csupo confirmed this rumour, right before {{Retcon}}ning it by having both characters appear in the same episode.

** Kimi isn't necessarily hated on ''Rugrats'', but her arrival on the show is associated with SeasonalRot. Here she's far more popular, and one of the biggest targets for shipping.

* ValuesDissonance: A few moments in the show can be considered this, for example, Chuckie and Chaz dressing up as geishas in order to respect Kimi's Japanese culture would now be seen as appropriating it.

** Tommy's fate in "All Broke Up." Rachel thinks he's been cheating and calls things off with him, the potential new girlfriend gets furious and thinks she's been set up, and of course Tommy's friends are furious that he lied to them.

* HilariousInHindsight:
** In the episode, "You-Gotta-Go", there is a character named The Shark who makes a brief appearance. [[Anime/YuGiOhZEXAL Come a few years later though...]] To top it all off, said character has purple hair.
** Tommy Pickles is shown to have a passion for filmmaking, [[Film/TheRoom just like a certain other Tommy]].

* CrazyAwesome: Dil, of course! Believes the world is shaped like a tetrahedron, can communicate with porpoises, walks backwards on his hands because he thinks it's a superior mode of locomotion - to name a few. He's also highly intelligent and creative - coming up with unique products to sell at school, and one episode implying he partied with aliens.

* ToyShip: Due to the characters being older, there's a lot of potential pairings hinted at:
** Kimi is revealed to have had a crush on Tommy and even carved their initials when she was younger.
** The ValentinesDayEpisode has Tommy dancing with Lil at the HighSchoolDance.
** The same episode has Harold pretending to be Angelica's date to make Sean jealous.
** Lil jokes that she finds Chuckie rebelling "kind of attractive".

** Chuckie and Lil seem to be the second-most popular pairing among fans of the show, usually as the BetaCouple to Tommy and Kimi. This is despite them getting even less deliberate ShipTease than Kimi and Tommy had, which is to say they had none at all. Although to the shippers’ credit, Lil and Chuckie were seen to have great chemistry as friends.

* FanPreferredCouple: Kimi and Tommy (half of the images of them on [=DeviantArt=] are them getting married). Which is why many people consider TP+KF that TheyWastedAPerfectlyGoodPlot.
