* SugarWiki/AwesomeMusic: [[https://www.youtube.com/watch?v=6P05NehzvGc The theme song]].
** SuspiciouslySimilarSong: The theme song sounds a lot like a sped-up version of Music/{{Bananarama}}'s famous 1983 hit "Cruel Summer." The 1998 cover by Music/AceOfBase falls in the middle between the two.
* FridgeBrilliance: The Warlords being creatures of stone at first looks like a gimmick that conveniently makes their deaths less objectionable. The fact it actually has a deeper meaning in that [[ExcaliburInTheStone Excalibur is a sword held in stone]] and thus stronger than stone is easily missed because it's said only once, in the second episode. It also doesn't help that the storyline makes the Warlords a lot more defeatable than by just Excalibur, because if that detail was adhered that'd make the other Knights borderline useless and Arthur battling Viper, the one human in Morgana's army, strategically inadvisable.
* SugarWiki/FunnyMoments: The show's humor is, for the most part, within expected levels. However, it ramps it up in "Viper's Phantom", not-so-incidentally the VillainEpisode, deriving its humor from showing the increasing frustration of the villains dealing with their ongoing defeats.
* HilariousInHindsight: The entire premise of the show has a collage football team transported into medieval Britain. Fast-forward a few decades or so and with the popularity of ''Literature/SwordArtOnline'', ''Literature/ReZero'' and ''Literature/{{Konosuba}}'', ''King Arthur & the Knights of Justice'' can be considered the proto-Isekai.
* TheProblemWithLicensedGames: The video game had very negative reviews and it's regarded as a terrible game. The thing, though, is that it had a start that should've spared it this fate. It was the first [[Creator/SquareEnix Enix]] game developed by an American company, Manley & Associates, and was supposed to get development time as it needed. The team also were enthusiastic about the project and in addition to using season 1 of the cartoon as a source dug deep into Arthurian lore to further dress up the game, leading to the inclusion of Hadrian's Wall, Tintagel Castle, Blaise, and a reference to Riothamus among others. Then the entire franchise was cancelled and the game was put through a final rush to become what it is.
* SeasonalRot: The show ran for two seasons but the second was marked by a lower animation budget and tacked-on AndKnowingIsHalfTheBattle epilogues.
** Just for fun, go to the characters page and try to guess which images are season 1 and which are season 2.
** The audio also got hit hard by budget cuts. Season 2 has a lot more "filler sound" such as grunts, yells, gasps, and the like, especially during combat. These sounds also got recycled, so sometimes a character will grunt in another character's voice because someone thought that wouldn't be noticeable.
* TheyWastedAPerfectlyGoodCharacter: Due to a large cast and only two seasons, this goes for somewhere between half to three quarters of the cast, and the villains get hit harder than the heroes, but the ones that stand out are:
** Sir Lug: The Knight who doesn't quite fit with the other Knights and would prefer to be back home safely more than anyone else. He got ADayInTheLimelight to provide counterwight to the other Knights' enthusiasm, prove himself, and earn his peers' respect, but that was all.
** Lady Mary: Mary's role in "To Save a Squire" clearly was ADayInTheLimelight material, but it built up well and provided the possibility for Mary to return for an adventure. Instead, she didn't and the show more or less pretended "To Save a Squire" didn't happen.
** The shield emblems: Not only do Lug's octopus and Zeke's hydra make no appearance at all in the entire franchise, but most of the creatures barely ever appear. Arthur's dragon (9), Lance's lion (4), and Trunk's ram (4) get enough appearances and/or focus scenes to be considered adequately used, but Wally's falcon (4), Darren's eagle (3), Breeze's sphinx (3), Brick's bat (2), Tone's serpent (2), Phil's panther (2), and Gallop's cerberus (1) all are scraping the barrel's bottom. On top of that, their origins are vague if not contradictory and it's only communicated inbetween-the-lines in "Darren's Key", "The Island", and "Quest for the Book" that the shield emblems can be summoned no more than once per mission.
** The Black Family: As far as the SNES game exclusive content goes, one of the most memorable moments is a trip to the Dark Forest (ie, the perished people place). And the most memorable characters there are the Black Family, consisting of Baron William Black, his daughter Mary, and his sons Richard and NoNameGiven. There's also mention made of William's father, John, who got the family cursed, presumably related to their semi-dead state. Mary tells you of this curse and how to break it, but the game gives no option to follow up on this. Once you've recovered the Knights Morgana murdered, all you can do is leave. On top of that, the Dark Forest and anything relating to that section of the game were clearly far from finished when the final deadline was given, because the dead all share the same two sprites: cloaked or zombie.
