History YMMV / TwentyFourLiveAnotherDay

* VillainDecay: In her first appearance, Simone proves to be quite cunning and resourceful, managing to outwit Jack and accomplish her mission, making her a deadly [[TheDragon dragon]] to her mother. By the fourth episode, this goes out the window and she ends up suffering all sorts of abuse and failures [[spoiler: such as accidentally killing her sister-in-law whose death she was trying to prevent... and then almost immediately getting hit by a bus moments later.]] By her final appearances she's reduced to a borderline IneffectualSympatheticVillain, a far cry from how she was when she was initially introduced.
* UnexpectedCharacter: Absolutely no one in-universe or out expected [[spoiler: Cheng Zhi]] as the final villain.

* WTHCastingAgency: Stephen Fry as the British Prime Minister, especially since most Fox viewers know him as the goofy psychiatrist from ''Series/{{Bones}}''.

* IdiotPlot: Margot Al-Harazi sends her daughter to find what her uninvolved sister-in-law knows about their drone hijacking plot and, after it turns out she doesn't know anything, to kill her and her young daughter just to be sure... after she's already released a video to the American and British governments announcing what she's done. It comes off as just a contrived way to send Margot so far over the MoralEventHorizon that even her daughter would turn against her.

* WhatAnIdiot: Simone Al-Harazi [[spoiler:has, under her mother's orders, already had one of her own fingers sliced off, and watched as she ordered the death of her sister-in-law and niece even though they posed no threat whatsoever to spoiling their plan. So when she winds up wounded and in hospitalized, forcing Margot to order her death to keep her quiet, she's still refusing to help at all and under the belief that her mother wouldn't try to hurt her. Jack actually says "screw it" at one point and is perfectly willing to let her die in the hospital when one of the drones Margot hijacked is ready to blow it up, quickly causing Simone to change her attitude and beg him to come back. This is actually rather realistic for abused, psychologically manipulated kids. It's still idiotic.]]

* FanPreferredCouple: Some fans rooted for Jack to get together with Kate Morgan, due to her being basically a DistaffCounterpart to Jack (i.e. a badass government agent who has no problem breaking the rules when necessary).

** [[spoiler:Cheng Zhi's return is completely spoiled by Tzi Ma being openly listed in the guest cast credits.]]

* AwesomeMusic: The [[https://www.youtube.com/watch?v=U1JyAIpbWZc "Street Chaos" teaser]] is set to Zack Hemsey's "Vengeance".

* CompleteMonster: [[spoiler:Cheng Zhi]]. See [[Monster/TwentyFour Monster.24]] for more details on what he did here to reach this special position of evil.

** The miniseries also features what was perhaps always the inevitable end of the "perimeter" motif, as Eric seems to become GenreSavvy and describes the terrorists as making one of their own. They're finished a few moments later.

** Kate Morgan has managed to get pretty popular after just a few hours thanks to her own pretty {{Badass}} behavior.

* LikeYouWouldReallyDoIt: [[spoiler:The "death" of President Heller]]. Even on a show [[AnyoneCanDie that kills off main characters left and right]], did not take the risk of killing off [[spoiler:the President of the United States of America while he was still in office]].

** The reveal that [[spoiler:Moscow is conspiring to start a war between the USA and China so that Russia can gain a strangehold on its Eastern European neighbors]] is eerily unsettling in light of the ongoing Ukraine crisis.
