History YMMV / IceAge5CollisionCourse

* {{Adorkable}}: Julian's always excited and happy in the same way as a little kid.
%%** Roger is extremely awkward.
* SugarWiki/AwesomeMusic: Buck singing a version of "Figaro's Aria" from ''Theatre/TheBarberOfSeville''.
* BaseBreakingCharacter:
** The DenserAndWackier approach to the series has seemingly reached its peak with the Shangri-Llama, a supposedly mystical shaman who will save the Earth from the asteroid. Is he a funny addition to the series or a stupid character already?
** Julian, on one hand he's seen as an unnecessary addition to a franchise that has already being criticized for having too many characters and his subplot with Manny and Peaches is very disliked, while on the other hand, he's one of the few characters of who you can genuinely root for and is shown to be a legitimate NiceGuy in comparison to the rest of the Herd in this movie.
* BrokenBase: Any movie series will have one by the time it reaches its fifth installment, so it's expected for there to be some divisiveness.
** Has the DenserAndWackier approach gone too far?
** Whether ending the series here is a good idea or not; while some die-hard fans may want the series to continue, especially due to this film's less-than-stellar quality being considered a disappointing end to the series, others wish that the 14-year-old franchise with increasingly negative reception be finally put out to pasture.
* EnsembleDarkhorse:
** The Scratazons from the "Spaced Out" mini-movie have become rather popular because... well, [[UsefulNotes/FurryFandom just]] [[GreenSkinnedSpaceBabe guess]].
** Roger is liked even by oppositers of the movie for being probably The OnlySaneMan among the cast and one of the few characters that was likeable and not annoying.
* FanonDiscontinuity: Many fans prefer to pretend this film doesn't exist, perhaps even more so than the other sequels. The above and below mentioned issues certainly play a part in it.
* ItsTheSameNowItSucks: One of the chief complaints against the movie is that it's unoriginal and not creative at all, and several critics contended that it felt more like a DirectToVideo film. Manny's domestic issues in particular are criticized for feeling like standard sitcom drama .
* JustHereForGodzilla:
** [[EnsembleDarkhorse Buck]] returning is one of the main reasons fans went to see the film.
** Also, Neil De Grasse Tyson. Some people just couldn't resist the chance to see him in a film like this one.
** Creator/NickOfferman as the feathered raptor Gavin attracted some viewers.
* MemeticMutation:
** For fans against the film, "let the asteroid hit" is a common response to the trailers.
** '''"[[WebVideo/FilthyFrank IT'S TIME TO]] ''[[WebVideo/FilthyFrank STOP!!!]]''"'''
** That, however, is a turd. [[labelnote:Explanation]]There's a scene where Crash and Eddy lick what is supposedly a rock after seeing Buck do so earlier (as a stand-in for relative age dating), then Buck says this line. Replace the rock with a good installment of a series or a good piece of media, and the turd with a bad one, and you have this meme in a nutshell.[[/labelnote]]
** "That's the ''stupidest'' thing I've ever heard!'' [[labelnote:Explanation]]A line uttered by Neil [=deBuck=] Weasel upon hearing the raptors' scheme to avoid the asteroid. Used as a response to stupid comments or ideas on forums or social media.[[/labelnote]]
* {{Padding}}: After the herd learns of the asteroid, they spend the second act simply marching from one set piece to another, and don't even reach Geotopia until the last 20 minutes of the film. There are way too many plot lines going on in this film.
* RescuedFromTheScrappyHeap: Widely considered to be one of the film's few improvements over its predecessors is that Peaches is significantly more tolerable and mature in this movie than in ''WesternAnimation/IceAge4ContinentalDrift''. If anything, she's arguably more mature than ''either'' of her parents.
* RootingForTheEmpire: Many critical reviews expressed a desire for the asteroid to actually hit to ensure no further movies will be made.
* TheScrappy: Brooke. Her [[UncannyValley character design is hideous]], as they gave a cartoony sloth human-like hair and a "dress" made from fur to really show that she's female. Besides, she is generally useless, barring a single scene, and seems to only exist to give Sid, [[ButtMonkey of all characters]], [[SatelliteLoveInterest a girlfriend]].
* {{Sequelitis}}: ''Collision Course'' is nowhere near the quality of ''any'' of the previous films, according to the critics. The idea of it being an unnecessary sequel is a prevailing theme in many reviews. The film holds the lowest critical score on Website/RottenTomatoes (16%), not just for the series, but for Creator/BlueSkyStudios as a whole. It was also far less successful at the box office than its predecessors (though still managed to be profitable). An interview indicates they have plans for '''[[http://www.flickeringmyth.com/2016/07/exclusive-interview-with-galen-chu-co-director-of-ice-age-collision-course-about-the-new-adventure-simon-peggs-return-and-the-franchises-continued-popularity/ a sixth film]]''', but said interview also took place before the film tanked at the box office.
** The closure of Creator/BlueSkyStudios pretty much guarantees that a 6th film won’t be made [[note]] though this may be for the best considering how utterly fed up critics and even audiences seem to have become with the franchise at this point[[/note]].
* SignatureScene: Buck’s reintroduction in which he sings “Figaro” is generally regarded as the one good, creative scene of the movie.
* {{Squick}}:
** Sid and Brooke becoming a couple becomes this when you realize Creator/JohnLeguizamo is old enough to be Music/JessieJ's father.
** Eddie very nearly licking a turd.
* TheyWastedAPerfectlyGoodCharacter:
** Shira went from being a major supporting character in the fourth film to an extremely minor character here. She has a minor subplot in which she and Diego are discussing having children and wanting to gain acceptance from the other members of the herd, and a brief scene at climax where she and Diego are Manny's right-hand-men, but she's barely in the movie. Several people questioned why they even bothered hiring Music/JenniferLopez to reprise her role that had barely any lines this time around.
** Fans were disappointed that Louis, who was also a major supporting character in the fourth film, only got a mere, silent cameo here.
** Buck's return to the film was widely well-received by fans of the franchise. Despite the character being brought back [[PanderingToTheBase solely to please fans]], these fans were frustrated when Buck made his grand return and [[DemotedToExtra didn't really do anything spectacular or important]] outside of his version of Figaro Aria.
** Some feel that since this film was hyped up to implicitly be the GrandFinale, they should've brought back characters from the previous films like Roshan, Carl and Frank, and the remaining pack of sabers from the [[WesternAnimation/IceAge first movie]], Fast Tony and Cholly from the [[WesternAnimation/IceAge2TheMeltdown second]], Scratte, the ''T. rex'' family and Rudy from the [[WesternAnimation/IceAge3DawnOfTheDinosaurs third]], or the surviving pirates from the [[WesternAnimation/IceAge4ContinentalDrift fourth]] for a major case of BackForTheFinale. Even more disappointing is the fact that this may never happen at all, due to this film's negative reception and low box office draws very likely [[{{Pun}} icing]] any chance of a sixth film.
** The Dino-bird villains get some flack for not being as interesting or memorable as the previous films' villains since their plan to prevent the heroes from stopping the asteroid is utterly illogical [[note]]Which gets {{lampshaded}} by Neil [=deBuck=] Weasel [[/note]]and they constantly fail at every opportunity. However, one of the things that makes them stand out is that they are the first and possibly only villains who redeem themselves at the film’s end.
* UglyCute: [[http://iceage.wikia.com/wiki/Roger Roger]] himself can be seen as this, since him is a Dromaeosaur, but his depiction, with his big eyes and lanky body, makes him so endearing and adorable.
* WereStillRelevantDammit: Jessie J only voiced a character to sing a song and that’s just about it.
----

* HilariousInHindsight: In the [[WesternAnimation/IceAgeContinentalDrift fourth film]], Shira [[BaseBreakingCharacter split the fandom]] due to many fans seeing her story as an inferior rehash of Diego's CharacterDevelopment from the [[WesternAnimation/IceAge original film]]. The writers seemed to have unintentionally followed this path, as Shira is DemotedToExtra in this film, which upset many fans when this happened to Diego in the other sequels.

* WinTheCrowd: The return of Buck was very well-received by fans.

%%* AudienceAlienatingPremise: How did we go from three prehistoric mammals trying to return a baby to his family to stopping an asteroid?

* CriticProof: At long last, the film breaks the franchise's established streak by averting this trope. Not only was it heavily panned by critics, but audiences were also less-than-impressed, causing the film to [[BoxOfficeBomb take in significantly lower profits than its predecessors]] and [[FranchiseKiller likely killing any chance of another sequel]].

* UglyCute: [[http://iceage.wikia.com/wiki/Roger Roger]] can be seen as this.

** Fans were disappointed that Louis, who was also a major supporting character in the fourth film, only got a mere, silent cameo here. To be fair though, they probably couldn't get Creator/JoshGad back to reprise his role.

** Buck's return to the film was widely well-received by fans of the franchise. Despite the character being brought back [[PanderingToTheBase solely to please fans]], these fans were frustrated when Buck made his grand return and [[DemotedToExtra didn't really do anything spectacular or important]].

* ArcFatigue: After the herd learns of the asteroid, they spend the second act simply marching from one set piece to another, and don't even reach Geotopia until the last 20 minutes of the film. There are way too many plot lines going on in this film.
* AssPull: The premise is that a herd of prehistoric mammals will save the Earth from an extinction-level-event, and it keeps going downhill from there.

* {{Narm}}: Many interviews with the cast members and spots called this, "the best Ice Age movie ever" and that couldn’t be farther from the truth.

* DarknessInducedAudienceApathy: Despite Scrat's scenes still being regarded as the highlight of the film, many are losing interest fast since it seems Scrat's purpose is only to cause catastrophe and constantly fail to get his acorn.
