History CharacterDerailment / LiveActionTv

** While Hopper thankfully got CharacterRerailment in Season 4, the aforementioned Mike dropped off so hard a lot fans (to the cast’s surprise) consider him TheScrappy — entirely because of how his character was introduced compared to who he is now. In Season 1, Mike is TheLeader of the kids, the one leading the mission to find Will and shows himself to be deeply caring to his friends as well his love interest Eleven. In Season 2, he’s a little more selfish in his pining for Eleven and antagonism towards Hopper for keeping her from him but is still shown to be a caring friend to Will, Dustin and Lucas, even if his leadership role has now gotten downplayed. In Season 3 and 4 however Mike has become a jerk who treats Will (who nurses a crush on him) poorly and worse still hypocritically gives Will a speech about growing up and not playing [=DND=] anymore whilst dating Eleven but as soon as El moves to California what does Mike do? Go back to [=DND=]. This wouldn’t be so bad if the whole first season wasn’t about Mike going above and beyond to find Will, so the fact he now treats one of his dearest friends with borderline apathy is too much for some fans. Not to mention his integral role among the kids has been effectively swapped out for Dustin with Mike getting degraded to Eleven’s cheerleader, making fans believe the Duffer Brothers simply don’t know what to do with him. Even Mike’s touted role as TheHeart can be considered an InformedAttribute in the later seasons.

* In ''Series/FamilyMatters'', one of ExtravertedNerd Steve Urkel's redeeming traits was originally that he was a personification of the [[AnAesop aesop]] "just BeYourself." The original appearance of his alter-ego Stefan Urquelle was merely a vehicle for {{Anvilicious}} preaching of this aesop. Unfortunately, then someone on the creative team decided that Stefan should become a regular part of Urkel's bag of MadScientist tricks; not only did this result in a BrokenAesop but the entire point of his character was lost.

** Finn suddenly feeling empathetic and forgiving towards Sheila, his biological mother, once more after recently having nothing but months of feelings of estrangement and disdain for her after being shot and held hostage with Steffy left to think he was dead, so much so that he started emotionally ''hugging'' her in his encounters with her before and during her trial in mid-2023 came off as off-putting to many viewers, especially his fans. Many viewers of the show, especially Sinn fans, have called out the writers for this over the lack of foreshadowing and accused them of [[DerailingLoveInterests intentionally making him unsympathetic]] before the big confrontation between him and Liam over the latter going behind his back with Steffy so that they can justify pairing [[CreatorsPet Liam]] back with Steffy [[TheScrappy despite how widely disliked he is by the fandom for his abusive and adulterous ways]]. It was also problematic in that this basically was seen as an attempt to deflect from the fact that Liam forcibly kissed Steffy ''twice'', and she pointlessly once more kept it a secret from Finn similar to the time she cheated on him and was potentially pregnant with his child (Which thankfully for Finn, was actually his own, but still was low of Steffy).

** In the end of 2022 and early 2023, Bill Spencer went from being the strong-willed billionaire that he was known for being into an EmptyShell that blackmailed Steffy despite promising not to previously. The problematic factor comes in when the explanation of this sudden change in attitude is over being rejected by Brooke and Katie made entire plot and reasoning seem misogynistic to some. Viewer backlash to this sudden change was so bad, that it was suddenly revealed he was undercover which [[AuthorsSavingThrow many believe was an immediate backpedal on the original plans for the arc]] since it differed immensely based on that Soap Opera Digest had said was planned for the upcoming weeks.
