New parents are usually as happy as can be. They look forward to raising their kids as idealized versions of themselves, or at least copies of themselves. It is not bad parenting; parents want their kids to share their cherished values and ideas, and avoid the mistakes they made growing up.
These kids ended up having their own views of how the world works. For better or worse, they don't share their parents' interests, they don't want to enter the same careers, or worst of all, they may not share their parents' political or religious views. This leads the parents to wonder, "Where did we go wrong?".
Classic set-ups include a girl with a domineering Stage Mom, or a son being forced to hunt deer in a Manly Men Can Hunt scene. In more dramatic works, a rebellious child might end up being downright criminal.
Very common in sitcoms.
Not related to tropes such as Gone Horribly Wrong.
- In Axis Powers Hetalia, the American Revolution is pretty much portrayed this way. Played for Drama, the scene with the rainy battlefield where a desperate England, with his army lost, attacks, disarms but still can't shoot America, before breaking down in tears, is a famous Tear Jerker. To quote America's thoughts... "You used to be... so big..."
- In Fairy Tail, Makarov says this word for word in the English anime when expelling Laxus (his own grandson) for endangering the lives of his fellow guildmates and trying to take over as Fairy Tail's guild master. While not outright stated in the original Japanese or the manga, the implication of Makarov's feelings is still there, especially seeing that Laxus Used to Be a Sweet Kid.
- Robin Series: Jack Drake has such a reaction to realizing his son is not who he thought he was, forbidding him from ever contacting the Waynes again or any of the friends he made through them and then mostly distancing himself from his son at home while policing his activities. Jack eventually does come around and accept Tim for who he is.
- Spoofed in The Emperor's New Groove, where Yzma, the Evil Chancellor, goes off on an outraged rant after being fired by Royal Brat Kuzco.
Yzma: How could he do this to me?! Why, I practically raised him!
Kronk: (Without a shred of irony) Yeah, you'd think he'd have turned out better.
- In The Land Before Time V, the gang meets Chomper, the baby T-rex they befriended in the first sequel. During the "Friends For Dinner" song, Chopper is collecting various leaves and other flora for his herbivore friends to eat. As he's doing this, his parents are watching (and apparently unclear on what he's doing) and one says to the other, "Sometimes I worry about that boy."
- In Everyone Says I Love You, there is a quick exchange between Alan Alda's character and his son over political beliefs. He playfully exclaims, "How did I end up with a kid on the other end of the political spectrum? How did I fail? Steffi, get me a copy of my will... and an eraser."
- Both the 1976 and 2003 versions of Freaky Friday or its many rip-offs utilize this trope but also subvert it in that in the end, it's shown that the teenagers and parents weren't quite as different as initially believed.

- Played in the most serious, dramatic, and painful manner possible in "The Force Awakens" with Han and Leia and their son, Ben Solo/Kylo Ren. They debate various potential reasons, from Vader's Force echo to the usefulness of Luke's training to the influence of Big Bad Supreme Leader Snoke. They try to bring him back home and for a moment he seems to respond to Han's plea but then cements himself in his grandfather's legacy by murdering his father in cold blood.
- Much of the focus of We Need to Talk About Kevin (and the Film of the Book) is Eva trying to work out whether she did do anything wrong during her school-shooter son's upbringing. While Eva seems to think that there was something wrong with Kevin from the moment he was born (he seemed to spurn contact and affection from the moment he left the womb), she is also well aware that she was a bad mother, and that this may have contributed to his apparent sociopathy. The question is not answered; Eva comes to no conclusion one way or the other, and the fact that she's an Unreliable Narrator means any thoughts she does have are suspect anyway.
- In Shaman of the Undead, this is the main line of tension between Ida and her parents. They had one girl as a "necessary minimum", expecting her to turn out to be a successful wizard like they are and get married to another well-born wizard, but she turned out to be devoid of magic and completely unwilling to settle down.

- 7th Heaven: The Kamdens have to deal with their rebellious, eldest daughter.

- This is what drives I Hate My Teenage Daughter.
- Invoked in The Suite Life of Zack and Cody episode "The Fairest of Them All" as a throwaway gag in which a girl named Tyreesha (the real one; as soon after this incident Cody gets Dragged into Drag entered into a child beauty pageant) angrily lets her Stage Mom know she wants to go to science camp instead of another pageant; leading to Tyreesha's mom using the trope name verbatim.
- Played for drama in The Golden Girls where Sophia has a strained relationship with her son, Phil, after he got married to Angela. This in turn, has Angela acting cold towards Sophia. After Phil passes away, Angela and Sophia meet at the funeral and get into an argument over Angela owing Sophia $47 in dowries. Eventually, Sophia reveals the real reason why she is so upset; Phil was a crossdresser and she wondered if she did or say anything to him that made him crossdress and blamed herself for it. Angela assures Sophia that regardless of what Phil was, he was a good man. Sophia completely breaks down in tears.

In one day, they discover their oldest son is cheating on his fiancee with his dental assistant; their other son dropped out of college a year ago and has been having an affair with their neighbor; and their daughter is a neurotic mess who talks to her parrot. The pilot ends with the two sitting on a couch and openly asking "what the hell happened?"

- Played with in this comic on DeviantArt.

His parents are ultra-liberal flower-child hippies, and extremely open-minded — and he rebelled by becoming a perfectly straight-laced IT graduate, working tech-support for Microsoft.
- In The Adventures of Dr. McNinja, the good Doctor's parents have this problem with him. Mitzi McNinja doesn't know how to raise ninja children, having become one by training, and Dan McNinja was never taught this, as it's supposed to be the mother who does this. They tried to teach him via Batman, but instead of a ruthless killer, they raised a vigilante doctor.
- Played for Drama in Worm, where Taylor's father Danny-an honest man from a working-class family who did his best to raise her alone after her mother's death-wonders what he did wrong to make his only daughter turn into a ruthless supervillain with an iron grip on the city's underworld.
- This is parodied in a sketch in a later ASDFMovie, where an officer brings a boy home and explains that he was caught "doing homework". The mother screams the singular variant of this phrase in horror.
- Moral Orel: Played straight on the [adult swim] show with a heavy case of Cerebus Syndrome. This is also a case in which it's seen as a very good thing that the kid will not end up like his parents.
- American Dad! devoted an episode on Francine and Stan figuring out what they did wrong with Hayley by cloning Steve and experimenting with parenting styles.
- It's eventually revealed that Francine's parenting alone would turn Steve into a lazy, slovenly, spoiled brat, whereas Stan's parenting alone would turn Steve into a cat-killing sociopath.
- On King of the Hill, most plots involving Hank and his son Bobby will take a turn through this trope. Most of the episodes end with Hank learning An Aesop about accepting that his son's talents and interests are different from his, then Status Quo Is God will kick in and they get to recycle the plot with a different disappointment of Bobby's.
- Finally averted in the Grand Finale when Hank and Bobby bond over Bobby's talent for grilling.
- A cartoon in Rocky and Bullwinkle featured a pair of parents who are jesters/clowns who has a son who wants to be a knight. Even the father flat out ask what did he do wrong.
