History YMMV / GalaxyQuest

* HarsherInHindsight:
** Watching Alexander talking to a dying [[spoiler: Quellek]] is already [[TearJerker the most heartbreaking scene in the film]], but it's much sadder now that Alan Rickman has passed on. Or the fact that he's parodying a character played by Creator/LeonardNimoy, who has also passed on little more than a year before Rickman. Little eerie.
** Tim Allen saving a group of refugees from a genocidal dictator plays rather differently after his notorious InsaneTrollLogic comparison of Republicans in Hollywood to Jews in Nazi Germany.

* FanNickname: [[StarTrekMovieCurse Star Trek 10]].

* SugarWiki/AwesomeMusic: The soundtrack by Music/DavidNewman is very good, particularly as it emulates many of the ''Star Trek'' themes combined with the humor and witty feel of Music/HenryMancini's score to the Creator/{{Disney}} movie ''Disney/TheGreatMouseDetective''. As a manner of fact, the main theme of movie is a SuspiciouslySimilarSong towards Mancini's theme to the aforementioned Disney film.

* HeReallyCanAct: Enrico Colantoni was thought of as just a lightweight sitcom star at the time, and seems the same for much of this movie. Then comes his ''devastating'' performance when Mathasar learns the truth about the Galaxy Quest show.

* NarmCharm: The first time the "By Grabthar's hammer" line is spoken, it's amusing, the final time, it's both [[TearJerker heartbreaking]] and [[AwesomeMoments awesome]], thanks to the irreplaceable acting power of the late, great Alan Rickman.

** Alan Rickman plays an actor admired by a large geek fandom. [[Film/HarryPotter Two years later...]]

** After Tommy is injured badly, he has to be carried out to the medical bay in a bit PlayedForLaughs. Daryl Mitchell, the actor playing Tommy, was in a motorcycle accident and was left paralyzed because of it. Now watch the scene with this fact in mind...

* CrossesTheLineTwice: The TeleporterAccident is so gross that it loops around to being funny again. If it was any ''less' gross, it wouldn't be nearly as funny. It's had quite a few shout outs over the years as a result.

* CompleteMonster: Despite being [[VileVillainSaccharineShow the villain of an otherwise funny film]], the bloodthirsty, sadistic [[BigBad General Roth'h'ar Sarris]] is a [[KnightOfCerebus brutal galactic warlord played dead straight.]] In pursuit of a mysterious and powerful device called the Omega 13, Sarris has launched a genocidal campaign against the naive and childlike Thermians and has wiped most of them out. He has been known to [[ColdBloodedTorture torture them to death]], put them to grueling work in his mines, and keep the women as sex slaves. In order to find information on the Omega 13, he tortured a Thermian commander for days, only killing her [[LovesTheSoundOfScreaming when he grew tired of the noises that she made]]. When the Thermians enlist the help of the cast of ''Galaxy Quest'', a TV show that they based their culture around while oblivious to the fact that it was a work of fiction, Sarris and his men invade the Thermian ship and try to force the show's star [[TheLeader Jason Nesmith]] to tell him how the Omega 13 works by torturing Thermian leader Malthasar, and threatening to do the same with Jason's LoveInterest and co-star Gwen [=DeMarco=]. When Jason can't answer and admits that the show isn't real, Sarris takes a sickening glee in forcing him to reveal his deception to Malthasar [[HopeCrusher in order to completely break his spirit.]] Afterwards, he tries to have all the Galaxy Quest actors thrown out of an airlock while slowly suffocating the remaining Thermians to death; when his plans are foiled, he manages to gun down most of the Galaxy Quest actors in revenge and only fails to kill them all due to the Omega 13 being able to turn back time. Not just brutal to his enemies, [[BadBoss Sarris is shown to be incredibly cruel to his own allies as well]], as demonstrated by him [[OffWithHisHead decapitating his lieutenant]] for failing to put up his ship's deflector shields in time, and leaving his men on the Thermian ship to die after rigging its reactor to explode.

* SpiritualLicencee: Series/{{TheOrville}} has a similar premise and oddball sense of humor.

* ValuesDissonance: In-universe example: The thermians have no concept of fiction and thus [[ActorRoleConfusion think everything from the show is real]]. When Jason explains it's not real the thermians consider it to be lying.

** Also, Jason is fighting Gorignak (the rock monster), and remarks that it "doesn't have any weak points." The line becomes especially ironic when another rock monster, Thardus, later makes an appearance in ''VideoGame/MetroidPrime'', who does have a weakness (using the Thermal Visor to locate the weak Phazon ore, expose it with firepower, and then finishing it off with firepower while using the Combat Visor).

* CultClassic: The movie was oddly mis-marketed to children upon initial release, but wound up playing ''far'' better simply as the AffectionateParody of ''Franchise/StarTrek'' that it was, and it maintains a big following of sci-fi nerds to this day.
