History YMMV / UchuSentaiKyuranger

** The show's opening theme, ''[[https://www.youtube.com/watch?v=bZ_MVNom4c8 LUCKYSTAR]]'', is an adventurous and futuristic tune with a tone that's optimistic even by Super Sentai standards. The lyrics seem to revolve around someone who wants to journey through the cosmos, most likely Lucky.

** Previously in {{LightNovel/Bakemonogatari}}, the character voiced by Creator/EriKitamura (Karen Araragi) referenced Dekamaster's catchphrase while talking with the character voiced by Creator/HiroshiKamiya (Koyomi Araragi). Now, not only did Creator/HiroshiKamiya's character here (Shou Ronpou) interact with [=DekaMaster=] himself here, a character voiced by Creator/EriKitamura also appeared in the same episode as the main villain!

* {{Narm}}: The Kyutama dance is hard to take seriously when it's literally a pelvic thrust. From Episode 12 onwards, the pelvic thrust is replaced with some arm-pumping motions.

* TheyWastedAPerfectlyGoodPlot: The season barely takes advantage of its space opera setting. By episode 6, they already arrive on Earth and the season takes place predominantly on the planet. Even when they do go to other planets, they make no attempt to create the illusion that they're alien worlds. There are no built sets, no props laying around, not even a color palette change. It's just [[BBCQuarry quarries, forests, beaches]] and downtown Tokyo, made worse by the fact that Toei reuses the same locations every season.

* WhatAnIdiot:
** In ''Space 6'', Lucky, Hammie and Garu arguing over leadership in front of the monster they are supposed to be fighting looks really stupid in light of the earlier events when not paying attention got everyone (sans Lucky and Champ) poisoned by Stinger.
** ''Space 8'' began with three members assigned on an away mission, while the other six were assigned a home mission to destroy five [[PlanetLooters Moraimarz]] in a row. The idiot part kicks in as everyone on the home mission except Raptor and Garu leave the mission to attend to other matters. [[spoiler: These actions caused Raptor and Garu to be captured.]]
** Stinger, of all people, gets caught up in this whenever he is dealing with his brother.

** ''Episode of Stinger'' [[DirectToVideo V-Cinema]]: [[BigBad Thunderbird]] is the Daikaan of Earth who [[ManipulativeBastard manipulated a village]] into lynching a [[HalfHumanHybrid half-alien girl]] named Mika Retsu so he could convince her to join Jark Matter. Though feigning care for her, Thunderbird views her as expendable and attempts to sacrifice her to kill the Kyurangers. After having her slaughter everyone in her village to prove herself to Jark Matter, Thunderbird "rewards" her by painfully mutating her with the power of Don Armage, leading her to beg Stinger to MercyKill her. After Mika fails to defeat Stinger, Thunderbird shows up to finish her off, coldly telling her [[YouHaveOutlivedYourUsefulness she is no longer useful to him]].

* BrokenBase: There is constant debate between fans as to whether Ryu Commander or Houou Soldier is the SixthRanger of the team (which continues to this day even after the series has ended). The debate was recently put to rest after [[Creator/HiroshiKamiya Hiroshi Kamiya]][[note]] Shou Ronpo's voice actor[[/note]] and [[Creator/KeisukeMinami Keisuke Minami]][[note]]Tsurugi Ohtori's actor[[/note]] have both gone on record during [[https://ameblo.jp/kamen-radiranger/entry-12338033780.html separate]] [[https://www.youtube.com/watch?v=KSX3uLLjOew interviews]] declaring Houou Soldier as the sixth Ranger. Further solidified by the ''[[KikaiSentaiZenkaiger Twokaiser x Gokaiger]]'' crossover special, where Houou Soldier is among the post-Gokaiger Sixths on the add-on piece for Gokai Silver's Gokai Cellular.

** [[Creator/KazuyaNakai Garu]] was actually once a [[Anime/DigimonSavers blue dog]] for another series. His profile makes it sound like he is going to act like Lucky's CanineCompanion makes it even more hilarious.

** Continuing the trend of ''Franchise/PrettyCure'' voice actresses voicing Sentai villains, Creator/EriKitamura will be voicing a Sentai villain who is themed after what [[Anime/FreshPrettyCure Miki]] is afraid of: [[WhyDidItHaveToBeSnakes an octopus]].
