History YMMV / IceAge

* WTHCastingAgency: Though fan consensus is that overall Denis Leary is perfect for Diego, anyone familiar with [[https://www.youtube.com/watch?v=-f_dxLiuXuw his standup]] would be surprised to see him play a mostly [[TheStoic calm]] character or just [[SesameStreetCred him being in a kids movie in general]], despite it not even being [[Film/TheSandlot the first one he's ever been in]].

** Scrat's scenes. While most agree his scenes are enjoyable, whether or not his scenes are the ''only'' [[JustHereForGodzilla enjoyable]] elements of these movies has been debated. Some feel his scenes are really the only worthwhile scenes, while finding the other characters [[FlatCharacter boring]] while others think both his scenes and the scenes with the herd are equally enjoyable, even in the sequels.

** Also Diego's resurrection; some fans thought his story would have had more power if he actually sacrificed himself (especially given TheyWastedAPoorlyCharacter how little many felt he got to do throughout the sequels), some fans are just happy he's alive, and others didn't necessarily want him to die but just wished there was more of an explanation as to [[AssPull how he came back to life]], especially given it's pretty clear in his "death" scene he was meant to die.

* FirstInstallmentWins: The first film is generally regarded to be very good. Meltdown is considered an alright follow-up to the original, but from there, the bases break.

%%* TastesLikeDiabetes: Some of the scenes involving Roshan and Peaches can feel like this. Specific examples?

* ToughActToFollow: While the sequels have their fans, most will agree that none of them hold a candle to the first movie.

** In 2002, there were no known mammals extinct or extant that closely resembled Scrat. Come late 2011, one was described and named ''[[http://en.wikipedia.org/wiki/Cronopio_(mammal) Cronopio]]''. (However, it was not a squirrel, but part of a now-extinct mammal group, the dryolestoids. Furthermore, it lived in the Mesozoic Era, not the Cenozoic as most of the other animals in the films are.)

%%* TheWoobie: Scrat, Sid, Manny, Ellie and Diego all have their moments.

** Roshan's aforementioned cameo in Ice Age Adventures of Buck Wild. While brief, it shows that despite everything and despite all the years having gone by, the Sub-Zero Heroes truly never forgot him if Ellie was able to hear about him during her opening monologue.

** While saying goodbye to Roshan, Manny tells him that they'll never forget him. This becomes blissfully ironic as Roshan is [[LongBusTrip completely forgotten about]] in the sequels. The best we got was a cameo in the beginning of The Ice Age Adventures of Buck Wild during Ellie's recap of the first 5 movies.

* GenreTurningPoint: The first film was the first major CGI movie that wasn't made either by Creator/{{Pixar}} or Creator/DreamworksAnimation to do well at the box office, being a 20th Century Fox production (even if Pixar's owner Creator/{{Disney}} later bought the rights when they bought Fox in 2019). As such, it proved that CGI movies were no longer just a minor novelty from two competing companies and helped make CGI films into a big figure in the mainstream box office.

** Sid/Diego is not an uncommon ship in the fandom and has persisted for quite some time (even with Diego and Sid gaining canon girlfriends) as an OppositesAttract sort of dynamic, built on the foundation of VitriolicBestBuds with an added dash of FoeYay from their interactions in the first film.

* TheScrappy:
** Crash and Eddie are considered a very bad example of ThoseTwoGuys, [[{{Padding}} and if you remove them from the fourth and fifth films, the story will be entirely the same]]. They exist only to be hilarious, but their brand of humor, behaving like idiots, gets old after thirty seconds for most people.
** The Baby (whose name is Roshan, according to supplementary material) from the first film, all thanks to its MemeticMutation and its [[UncannyValley rather hideous looking design]].

* TheyWastedAPerfectlyGoodPlot: That entire [[spoiler:herd of mammoths]] that appear at the end of the second movie is never followed up on.

%%* TheWoobie:
%%** Scrat, Sid, Manny, Ellie and Diego all have their moments.
%%** Add Louis as of the fourth film.
%%** Scratte, to a certain extent.

** This wouldn't be the last time [[WesternAnimation/{{Encanto}} John Leguizamo would play an outcast among his family]].[[note]]Bit more tenuous, but that latter film's setting of Colombia is also known for having once been inhabited by giant ground sloths in the Pleistoscene[[/note]]

* FranchiseOriginalSin: The first film contained a decent amount of ToiletHumor (Sid stepping in the glyptodont poop), adult humor (Sid saying that a girlfriend would "go all praying mantis" on him, amongst other things), and modern references (During the montage, a glacier was seen acting like a passing bus). However, this was underplayed compared to the sequels (In the case of the modern reference, it was just there for a quick joke), and the first film still had enough heart to make up for all of it. And furthermore, all the major characters had a purpose to their purpose and genuinely contributed to the narrative, whereas several characters (both old and new alike) in the sequels would end up coming across at times as having no real reason to be there at best and [[DemotedToComicRelief reduced to pointless or annoying comic relief]] at worst.

** Even those who were lukewarm on even the original have said that [[Creator/JohnLeguizamo Sid the Sloth's antics]] or the chemistry between Creator/RayRomano, Creator/DenisLeary, and Creator/JohnLeguizamo made the non-Scrat scenes bearable.
** Some people (*cough* furries) are just here because they find Diego attractive.

* FunnyAneurysmMoment:
** Diego's line "''can't have one of your own, so you want to adopt''", while only meant at the time as [[DeadpanSnarker snark]], becomes much harsher after the reveal that Manny's [[spoiler:mate and child were killed by humans]].
** Before the heroes enter the ice cave in the first film, Sid is joking around by pretending to be impaled in the neck with an icicle. [[spoiler:How does Soto die again?]]
