* SugarWiki/AwesomeMusic: Despite the series not shining as much as the recent predecessors, at least up to the first one-third, its soundtrack is definitely on par with others'.
** Gosei Great's theme song, "''Kōrin! Gosei Great''", is a ''must'' track.
** The battle theme: "''[[OverlyLongName Tatakae! Soshite katte wo e yo!]]''".
** Double that for [[DancingTheme Gotcha Goseiger]]. [[RearrangeTheSong Both versions]].
*** Correction; [[http://www.youtube.com/watch?v=UHCjHAY-HU0 all THREE versions]]
** Gosei Knight's [[http://www.youtube.com/watch?v=39xDB6Kto2g theme]] has a really catchy tune too.
** Datas Hyper's theme song definitely counts. Bonus points for the [[Franchise/MetalHeroes nostalgic feeling you get by listening to it]].
* BigLippedAlligatorMoment: Exotic Brothers. They even outright say that [[ItOnlyWorksOnce it's a one-time thing.]]
* BizarroEpisode: Epic 7. Fits the trope to a T.
** Epic 23. [[spoiler:At least until the end of the episode, which sets up the Abare Headder.]]
* BrokenBase: How Western Sentai fans feel about ''Goseiger''. They either like it and the throwbacks to previous Sentai series (including ''Zyuranger'', ''Dairanger'' and ''Magiranger'') or they hate it because of bad characterization, uneven writing, [[MerchandiseDriven gimmicks and reliance on them]]. Things cooled down once Gosei Knight joined the cast, but the show is still subject to intense scrutiny.
** It doesn't help that it came after the highly acclaimed ''Series/SamuraiSentaiShinkenger'', and when the double whammy of ''Series/PowerRangersSamurai'' (the return of the series) and ''Series/KaizokuSentaiGokaiger'' (pirates, nostalgia and sheer awesomeness) hit in late 2010, they completely overshadowed ''Goseiger'' (Although in the case of ''Samurai'', it's because it's commonly seen as a terrible season).
** Points generally used in favor of the series include its awesome mecha fights and interesting villains, but offset by criticisms of its weak heroic cast and bad writing.
** With [[http://www.virtualpressoffice.com/publicsiteContentFileAccess?fileContentId=850069&fromOtherPageToDisableHistory=T&menuName=Events the confirmation]] that the series is to be adapted as the 20th anniversary series, ''Series/PowerRangersMegaforce'', instead of the much more desirable ''Gokaiger'', the criticisms are starting again. Though it was later eased somewhat when it was revealed that Megaforce would combine ''Goseiger'' and ''Gokaiger''.
* CompleteMonster:
** Robogog, the third BigBad of the series, is a cruel and callous dictator who rules over his empire with an iron fist. Prior to his mechanization, when the people of Matrintis begged him to help them as their city is about to sink into the ocean, he concludes that fear is the most effective way to control everything. Unlike the benevolent Mons Drake and Makuin, Robogog treats his subordinate like crap, such as beating them up, calling them "low-specs", or installing Punishment Bombs on both Metal Alice and Buredoran to keep his power and influence only for himself. When questioned by the Goseigers over his BadBoss attitude, Robogog replies by telling them about his aforementioned backstory, implying that he has already abandoned what's left of his humanity a long time ago. He even attempts to nuke the entire Japan in an attempt to kill the Goseigers. Robogog's actions makes it ''very'' clear that he only cares for no one but himself.
** Buredoran, also known as [[spoiler:Brajira]], is the Sentai equivalent of Lucifer; [[spoiler:a cunning and treacherous FallenAngel with a [[DarkMessiah massive messiah complex]] who wants to destroy the world and remake it in his image as its ruler.]] He was manipulating the three villain groups from behind the scenes to gain more power before [[ChronicBackstabbingDisorder backstabbing them in cold blood]] when they were no use of him, [[KickTheDog including Metal Alice]], who treated him fairly while his memories are still in Robogog's possession. [[spoiler:After revealing his true colors to the Goseigers, Brajira makes his move by turning Gosei Knight into his lackey, and then have his Dark Headders killed off to become [[DoomsdayDevice Doomsday Devices]] for his EvilPlan. He even calls the Gosei Angels "half-assed", mocks the spirits of his bosses for their failures, and dismisses the Goseigers' ArmorPiercingQuestion as "meaningless". Not even his final defeat at the hands of the Goseigers could stop him, as he pulls a ThanatosGambit to ensure the destruction of Earth. An OmnicidalManiac at heart, Buredoran/Brajira is one of the most dangerous Sentai villains of recent times that the franchise has to offer.]]
* EarWorm: The ending theme "Gotcha* Goseiger".
--> ''Sora ni kagayaku'' Rainbow! (Rainbow!)\\
''Seigi no nakama shugo!'' (''Shugo!'')\\
''Chikyuu no'' Power ''Tensou!'' (''Tensou!'')\\
''Muteki no tsuyosa'' [[StealthPun Five Star]]! (Star!)
** And now it's [[RearrangeTheSong remixed]]. Double the EarWorm!
** Have you listened to the song Moune danced to in Epic 11?
* EnsembleDarkhorse: Magis.
* FanNickname: [[http://img263.imageshack.us/img263/3491/56789864.jpg Hyper Change Headder]] = "[[SuperMarioBros Bullet Bill Headder]]"
* FanPreferredCouple: As of yet there's no OfficialCouple on the show, but some fans thought that Hyde and [[spoiler:Magis]] would have [[HoYay gone well together]] and were disappointed his appearance on the show was brief.
** [[ChildhoodFriendRomance Alata and Eri]] is also present as a fan couple, with a bit of [[BelligerentSexualTension Hyde and Moune]] in the mix, making these pairings ShipMates.
* HesJustHiding: Up until the very end, there was a strong group that believed [[spoiler:Magis]] would return at ''some'' point, looking for clues where clues were not.
* HilariousInHindsight: For the record, the word "Tensou" has nothing to do with [[http://knowyourmeme.com/memes/tenso this]].
** As noted above, Metal Alice's voice actor was previously Yoko... [[spoiler:while Metal Alice got StuffedInTheFridge, Yoko became known as [[FanNickname 'Doombitch']] for inflicting that fate on two guys in succession.]]
** Landick Gosei Great's FinishingMove has been described as a drill [[KamenRider Rider Kick]]. Then ''Series/KamenRiderFourze'' happened...
* MagnificentBastard: Buredoran/[[spoiler:Brajira]].
* {{Narm}}
** The [[MonsterOfTheWeek MOTW's]] "ominous buzzing" sounds like farting at points.
** Kinggon and Makuin's Yuuma Buster sounds awesome... But then you see the posture that Makuin and Kinggon take to execute the move, [[FreudWasRight with Makuin pretty much bending over while Kinggon stands behind him]].
* NarmCharm: Gosei Knight's [[LargeHam hammy tendencies]] during his debut make him theatrically heroic.
* SignatureScene: [[spoiler: Alata punching out the darkness controlling Gosei Knight]] has become this. Even those who haven't seen the show know of this scene.
* SoOkayItsAverage: The general consensus. Being bookended by ''Shinkenger'' and ''Gokaiger'' doesn't help.
* SpecialEffectsFailure: Buredoran of the Chupacabra's claws are clearly EVA or a similar material, given how impossibly flexible they are whenever he moves his hands.
* {{Squee}}: A blink-and-you'll-miss-it moment in Epic 21. Takeru ([[Series/SamuraiSentaiShinkenger not that one]], [[Series/HikariSentaiMaskman or the other one]]), the boy who ordered the birthday cake that Eri's rushing to complete, shows up with his baby sister Hiromi, saying that the cake's for her ''first birthday''. The camera pans over, and with uncanny timing Hiromi smiles into it. Cutest. Thing. Ever.[[note]]Of course it's probably just the baby's RealLife mommy [[EnforcedMethodActing making faces beside the camera]]...[[/note]]
* TearJerker: Epic 41. Poor Koro; it's like ''TheIronGiant'' all over again.
* TheyWastedAPerfectlyGoodCharacter: The Landick siblings are the most underutilized characters in the show. One of ''Goseiger's'' problems are a little bit too much focus on the Skicks, especially Eri (Gosei Knight as well for being the only character that has a story arc), which is carried over to ''[[PowerRangersMegaforce Megaforce]]''. [[TheLancer Agri]] in particular could play [[WhatYouAreInTheDark a similar role to]] [[GoGoSentaiBoukenger Bouken Black Masumi]] as hinted in the first episode but was scrapped later on.
** Fans will never know details about [[spoiler:Burajira's past aside from him betraying the other Gosei Angels. Is there a catalyst for his traitorous side? Is he a Skick Landick or Seaick?]] Since the series is over none of this will be answered. On the other hand, some people feel that we didn't really ''need'' to know what his deal was.
* TheyWastedAPerfectlyGoodPlot: The origins of Knightic Power. It was never really explained. It would be really cool if it was related to a secret or ancient tribe. The same applies to Gosei Knight, who could perfectly be a lost ancient warrior from Gosei World instead of a Sentient Headder.
** During their battles against Warstar, Alata had personal battles against Dereputa. The same kind of happened between Agri and Kingugon during Yumajuu arc (but only towards the end of the arc, thus making it another example of this). Why couldn't we have the same during Matrintis arc, but with Hyde? His water based powers and analytical strategic mind would be used in a great manner if put against a stronger Matrintis's general.
** The Gosei World is not shown (or at least details on the Angels' daily life or tribe rivalry) at all.
** More use of combined elemental attacks would be interesting, like Wind+Ice or Water+Land or Thunder+Water. Those could be used in several creative ways.
** Magis, who created a lot of fan speculation, ended up being not very important outside of a few episodes.
* {{Vanilla Protagonist}}s: The Goseigers themselves.
* VindicatedByHistory: ''Goseiger'' is not that well-received by the fans, [[OvershadowedByAwesome especially since it was pitted together with]] ''Shinkenger'' and ''Gokaiger''. However once ''Go-Busters'', ''Kamen Rider Wizard'' and ''Megaforce'' came into the picture it received less hate compared to when it just started, making this trope a common cycle among Toku series in Japan. Getting an (arguably) better translation (by sub group Millionfold Curiosity) may have helped too.
* {{Woolseyism}}: The Millionfold Curiosity subtitles translate the monster names so that Western viewers can tell what movie they'r derived from.
