* TheCastShowoff: He sings most of the review of ''Film/TheManWhoFellToEarth'', to the tune of various Music/DavidBowie songs, along with WebVideo/TheNostalgiaChick, WebVideo/ToddInTheShadows, Allison and [[WebVideo/YouCanPlayThis JewWario]].
** He also has one of the best solos in WebVideo/TheNostalgiaChick's ''Theatre/LesMiserables'' review.
** Oancitizen opens the Channel Awesome Holiday Greetings with a one-person quartet choir.
** Teased in ''WebVideo/ToBoldlyFlee'', where he desperately ''wants'' to show off his singing talent, but doing so would blow his cover as a mute.
** Likewise in WebVideo/TheNostalgiaCritic's review of ''MoulinRouge'', where he gets '''really''' angry to find that he wasn't invited to sing in their musical review.
** After not being allowed to sing became something of a running joke ("It is literally the only character trait that [[WebVideo/TheNostalgiaCritic Doug]] has ever written for me!"), his character was justifiably smug about being prominently featured in the Nostalgia Critic's ''Film/LesMiserables2012'' review.
--->'''Oancitizen''' (to the tune of "At The End of the Day"): I might have known the cat had claws, I might have known the bitch could bite, I might have guessed your singing secret--
--->'''Linkara''': Okay, if you're going to insult me, don't do it in song.
--->'''Oancitizen''': Fine. I'll just say it's my time to shine and shut the door on you. [Does so.]
** He decided to make his review of ''Film/BeautyAndTheBeast'' a musical, parodying the [[Disney/BeautyAndTheBeast Disney version]] despite it being mentioned that's not the one he's reviewing.
* CreatorBacklash:
** [[https://twitter.com/KyleKallgren/status/247200946793373696 His]] [[https://twitter.com/KyleKallgren/status/247201953988370432 moniker]]. As of the ''Mister Lonely'' review, he's dropped it from the title sequence and goes by just his real name.
** Kyle's expressed regret about his ''Primer'' review, feeling he was way too hard on the film.
** He also turned against the ''Spring Breakers'' episode just a day after its release, admitting it wasn't his best work. While he considered doing a follow-up video to it, Kyle eventually decided on just covering those aspects next time he reviews a Korine film.
** Kyle's largely turned against his pre-''Melancholia'' reviews, feeling he was trying too hard to be funny over being informative. As such, many of them now have disclaimers saying that the video is "a work of satire and does not reflect the critical opinions of the author".
** For whatever reason, he deleted his review of Creator/SteveMcQueen's ''{{Film/Shame}}''.
** Upon DavidBowie's death, he posted on Twitter a link for his review of ''The Man Who Fell to Earth'' with "[[https://twitter.com/kylekallgren/status/686597294284750848 For those who like this silly thing...]]". Whether it's backlash or SelfDeprecation is unclear.
* EloquentInMyNativeTongue: He admits that he's not all that skilled with Dutch, although he has some knowledge; he spent part of his childhood in the Netherlands and even went to an international school there.
** His review of ''Nightwatching''/''Rembrandt's J'accuse'' opens with him addressing the viewer in Dutch, until the cameraman (actually his brother) cuts him off complaining about his terrible accent.
* FandomNod: ''The Origin of Escargoancitizen'', a live-action fan fic about Oancitizen turning into a snail, which was written InTheStyleOf ''Manga/{{Uzumaki}}''. Escargoancitizen has also made appearances in few other places, including a cameo in ''WebOriginal/ToBoldlyFlee''.
* GermansLoveDavidHasselhoff: Kyle has somewhat of a following in Russia, if the various Russian subs found on YouTube are any indication. So do most of the TGWTG contributors, though.
* MissingEpisode: The sans-commentary version of "The Girlfriend Experience" (which he felt completely misrepresented him) and "What Is It?" which got removed after Crispin Glover took umbrage at its existence. (To be fair, "What Is It?" is not commercially available in any format and it is only shown by Glover himself at private screenings. Kyle admitted in the review that the version he watched was by necessity pirated.)
** His Pinocchio episode also has gone missing.
** As of 2016, the only available version of the ''Melancholia'' review is a fan mirror of Part One subtitled in Russian. Part Two appears to have vanished in all forms.
* OldShame: When he posted the old review of ''The Girlfriend Experience'' on TGWTG, some comments came in, which he agreed with about the review coming off as SlutShaming, and he contemplated removing the review altogether. He did say the intent wasn't to mock Sasha Grey for her adult film work, but the message he meant didn't come across clearly.
* OneOfUs: In his [[http://blip.tv/brows-held-high/bhh-ken-park-commentary-4500529 commentary]] for his review of ''Film/KenPark'', he mentions using TVTropes to find films to review when he started the show, particularly on the {{Euroshlock}} page. He has now taken on ''Film/WRMysteriesOfTheOrganism'', ''Film/SweetMovie'', ''Exterminating Angels'', and ''Film/ASerbianFilm'', along with several of the American examples that were on that page.
** Midway through the first part of his review of Melancholia "By the way, TVTropes thinks I'm Catholic. Don't know why."[[note]]It's probably due to an offhand comment he makes during ''The Devil'' review ("I never went to Catholic school!") being mistaken for sarcasm.[[/note]]
** Downplayed defiance: after using footage from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' to kill the viewer's arousal, he confessed on Twitter that he was not, in fact, a [[FanCommunityNicknames brony]].
** He plays ''VideoGame/GrandTheftAuto'' and watches ''Franchise/StarTrek''. And is such a fan of ''VideoGame/{{Civilization}}'' he uses the "Our words are backed by nuclear weapons" quote in a review.
** [[https://twitter.com/KyleKallgren/status/467516128177434625 He demands our edits! Appease his ego!]]
* RealSongThemeTune: "Procession of the Nobles."
* RedStringOfFate: Kyle and his artist discovered only AFTER they agreed to work together that his artist lives only 4 blocks from him. They've since become not just coworkers but inseparable best friends, to the point of people thinking they're dating or even joking that they're married.
* RuleThirtyFourCreatorReactions: He's somewhat bemused by all the fangirls and SlashFic he's received already.
* ScrewedByTheLawyers: In the Blip era, ''What Is It?'', as noted above. In the YouTube one, most of his early work is not found in his account, but fan ones due to this ("Just curious, why isn't there a copy of that one on your channel?" "copyright botz").
* WhatCouldHaveBeen:
** Kallgren stated that, at one point, he thought of being an actor.
** During the break between ''Melancholia'' and ''Mister Lonely'', Kyle suggested a temporary series where he would rewatch the films he reviewed early on and recap them with a new perspective. He eventually discarded that for a new ''Between the Lines''.
** There was going to be a joke in the ''Mister Lonely'' review involving the scene in ''Film/GrizzlyMan'' where Werner Herzog listens to the recording of Timothy Treadwell being eaten, only with the audio replaced. Kyle ended up cutting the gag out.
** Another canceled video was one where Kyle would review ''Film/CitizenKane'' while drunk. In his own words, "getting sloshed for a joke just came off as sad the more I thought about it."
** The "Between The Lines" episode on {{Franchise/Batman}} originaly started out as a [[WebVideo/AtopTheFourthWall Linkara]]-style [[https://twitter.com/KyleKallgren/status/609978624687611904 voice over of his origin story]], but was cut for being indulgent and [[TooSoon unintentionally evoking the Aurora massacre]].
