History YMMV / HolyMusicalBatman

* GeniusBonus: The one Gothamite [[AccidentalMisnaming repeatedly calling Superman "Captain Marvel"]] is already funny. But it gets even funnier when you remember the original [[ComicBook/{{Shazam}} Captain Marvel (aka Shazam)]] was created as a Superman knockoff. He actually ''surpassed Superman in popularity'' for a couple years, until DC Comics sued Fawcett for copyright infringement over it. So, it was an easy mistake to make!

* OlderThanTheyThink: While the idea of [[ComicBook/Shazam Captain Marvel/Shazam]] being more recognizable than Superman is a funny joke in this show, considering how Superman is now considered the iconic, archetypal superhero that Shazam copied, back in late 30s-40s ''Captain Marvel'' comics routinely outsold ''Superman'' comics. It wasn't until DC won its copyright infringement lawsuit against their rival in 1948, forcing ''Captain Marvel'' out of publication for decades, that ''Superman'' established dominance.

** In the end, why did Penguin kill himself when Robin caught him? Was it that he was DrivenToSuicide after Sweet Tooth killed Chilly Willy? Did Sweet Tooth intimidate him into carrying that Fruit Gusher? Or did Penguin feel that Sweet Tooth would do something worse for letting the bird get him?

** Batman and Robin's relationship is treated more as a [[HeterosexualLifePartners brotherly]] relationship than father-son.

** The fate of Robin is determined by a poll, created by Sweet Tooth.

[[spoiler: When Son or Daughter is chosen to die, Mother cries out, "If given the choice to kill any one of us, [[TakeThatAudience who would chose one of the children?!]]"]]

* SugarWiki/AwesomeMusic: The whole thing.

* UnexpectedCharacter: Rather than doing the obvious and having the Joker, Poison Ivy, Scarecrow or some other well-known Batman villain as the Big Bad, the makers of ''HMB'' dug up Sweet Tooth, a C-list Batman villain who has had exactly two appearances in official Batman media. First as the villain in an episode of The New Adventures of Batman, where he commits crimes with a candy motif and weaponised sweets: a corny villain, even by the standards of the cartoon he was in. His second appearance was a cameo in Batman: The Brave and the Bold. Understandably, Sweet Tooth never caught on, and with the new, darker age of Batman stories, has been almost completely forgotten and ignored by all. Except this musical, that is. They even manage to go the extra mile and actually make him threatening. [[BewareTheSillyOnes Completely ridiculous, but threatening.]] He ends up playing like a candy-obsessed Joker.

* WhatAnIdiot: All PlayedForLaughs.
** Sweet Tooth has established himself as a potent threat who has cowed the other villains in Gotham to follow his bidding, including Poison Ivy and Penguin. In the second act, he uses a people-bomb to attempt to knock out Robin and Rachel Dawes, whom Robin is rescuing from a mugging. Robin shows that he can at least fight Sweet Tooth's mooks to a standstill to buy Rachel time to run. Sweet Tooth makes candy puns and hands out various sweets to Robin.\\
'''You'd Expect''': Robin to remember the candy is poisoned, as would Rachel, and realize this is a gimmicky ploy. Batman warned him not to have a bite in Act One.\\
'''Instead''': Robin keeps handing the Smarties and Almond Joy bars to Rachel, who takes time to nibble on them discreetly rather than make her exit as the superheroes duke it out.\\
'''The Result''': While these candies weren't poisoned, it's because Sweet Tooth has bigger plans. The candy distraction was all the time he needed to get the jump on the two. His sidekick and girlfriend Baby Candy successfully knocks out Robin while Sweet Tooth incapacitated Rachel with a bubblegum gun. Then on a recorded video, [[spoiler:he murders Rachel while a bound Robin is ForcedToWatch, to demonstrate the potency of his Warhead]].
** Meanwhile, Baby Candy got knocked down courtesy of Sweet Tooth. Robin abandons his fighting the mooks to help her to her feet, asking if she's all right. Baby Candy then says that the hit felt "like a kiss" when handing him a chocolate Kiss.\\
'''You'd Expect''': Robin to not ponder the meaning of this and either get her to a hospital for her injuries or arrest her. She may have been hurt but she's still a villain.\\
'''Instead''': He spends a few seconds looking at the chocolate to figure out what she meant.\\
'''The Result''': Baby Candy successfully sedates him with a hypodermic needle, causing him to collapse.
** In the climax, a fired Alfred returns to Bruce's side when Sweet Tooth takes Robin hostage and delivers an ultimatum to the city. They reunite, no hard feelings from Alfred, and discuss what to do to save Robin, stop Gotham's water supply from being poisoned, and take down Two-Face's heist.\\
'''You'd Expect''': They would agree that Sweet Tooth is the higher priority. Two-Face is considered a joke villain, and no one cares about two-dollar bills. Batman can use the plane to take down the Warhead or deposit it, while Alfred saves Robin. In-universe he's considered a MasterOfDisguise by Bruce's standards, and [[spoiler:Spiderman to boot]].\\
'''Instead''': They split up as Bruce chooses to save Robin and Alfred goes to stop Two-Face.\\
'''The Result''': Batman tweets on social media that Gotham better save Robin, causing citywide panic. This motivates President Obama to get involved. He calls Superman.\\
'''You'd Then Expect''': The President would tell Superman to save the citizens by taking down the Warhead.\\
'''Instead''': He orders Superman to arrest Batman. Even Superman questions this because Batman is a "butthead" but has good intentions.\\
'''The Result''': Superman wastes time fighting Batman when he could have stopped the Warhead.
** Sweet Tooth barricades the town square and is preparing to kill Robin. All too soon, Batman appears, armed, and soon firing upon the villains. They go MassOhCrap that Sweet Tooth apparently didn't know Batman had a plane.\\
'''You'd Expect''': He'd have the villains use Robin as a HumanShield, warning Batman that if he keeps firing on them, his Boy Wonder will be birdshot.\\
'''Instead''': He takes Robin with him to the abandoned candy factory, and the villains sensibly flee on realizing they have no leverage.\\
'''The Result''': Sweet Tooth is alone when Batman confronts him, and his new HumanShield doesn't last long when he tries tossing Robin into a vat of boiling chocolate. [[spoiler:To top it all off, he thinks that Batman isn't man enough to kill him because Batman is a hero. Batman shows-- with his fists-- that he begs to differ]].
** Superman confronts Batman when he's about to chase Sweet Tooth into the abandoned candy factory. He says he's under orders from the President to arrest Batman and save the citizens. Batman calls out Superman for being LawfulStupid, and no one is stopping him from rescuing his partner.\\
'''You'd Expect''': Considering Superman has SuperSpeed, which he has boasted about, and enough strength, that he would do what he does later: grab the Warhead and toss it into the sun.\\
'''Instead''': He follows orders.\\
'''The Result''': Batman, being [[CrazyPrepared Batman]], reveals he pocketed the Kryptonite he keeps for emergencies. Soon Superman is down.
** Then there is the issue with the water supply. Gothamites lament that this is the fifth time that a villain has poisoned the water.\\
'''You'd Expect''': By this point that the Gotham citizens would buy bottled water rather than get it from the tap, as people would during a hurricane or water shortage. After all, Gotham doesn't have its own bottled water plant so there are lesser chances of Sweet Tooth's warhead affecting more than one supply of a necessary resource.\\
'''Instead''': Everyone resigns themselves to death when they vote to [[spoiler:save Robin rather than save themselves]].\\
'''The Result''': Superman of all people [[spoiler:has to reverse time to stop the warhead]].

* FoeYay: "To Be a Man" is this in song form.
** The CatFight between Batman and Sweet Tooth.

*** To be fair, Robin in this musical borrows more from ''Series/Batman1966'', where he was played by 19-year-old Burt Ward (and which has [[YMMV/Batman1966 its own HoYay reputation]]).

* CreatorsFavoriteEpisode: In a very classy move, Creator/DarrenCriss praised this show -- the first Starkid show he had no involvement in -- as having his favorite music by far of all the Starkid canon, and said Nick Gage's songwriting was far superior to what he would've come up with. He even said that he played "Dark, Sad, Lonely Knight" at the party when he received his Emmy Award.

** 'The Dynamic Duet' UpToEleven. In addition to featuring Batman and Robin dancing around in [[FormFittingWardrobe spandex]] and singing about how much they [[HeterosexualLifePartners care about each other]], Robin having an [[CrushBlush interesting]] [[AmbiguouslyGay reaction]] to Batman touching his cheek, the song ends with Robin jumping into Batman's arms and kissing him on the forehead

'''Instead''': He orders Superman to arrest Batman. Even Superman questions this, because Batman is a "butthead" but has good intentions.\\

** [[WesternAnimation/TheLEGOBatmanMovie The LEGO Batman Movie]] is also suspiciously similar story-wise. There is a brooding Batman that beats up criminals for fun, a BeleaugeredAssistant Alfred that treats Bruce like a son and is taken for granted, and a Boy Wonder who breathes life into Batman's life.
--> '''Nick Lang:''' Yeah we saw the Lego Batman Movie, and... well, it was a lot like our show

** For pragmatic reasons, Ivy's appearances are downplayed in Act Two so the same actress can play Baby Candy. Could it also be that Ivy feels guilty for inspiring Sweet Tooth to target Robin and feels she should stay out of the scheme for as longa s possible? She looks discomfited when he thanks her for giving him the idea and hints that he will murder Robin. In the comics, some of her iterations are a FriendToAllChildren. (One notable comic had her and Harley Quinn abandon a bank heist to save a girl that another villain tried to kidnap and beat up.)

** [[WesternAnimation/TheLEGOBatmanMovie The LEGO Batman Movie]] is also suspiciously similar story-wise.

** The scene where Sweet Tooth sends some "disturbing footage" and an ultimatum. He reveals that [[spoiler:he's taken Robin and Rachel Dawes hostage, and as a giant candy Warhead. Scary? Not until his mooks force Rachel's mouth to the Warhead, making her take a lick after covering her nose, and her head explodes. (Take their word for it since this show has few special effects.) Robin throughout it has a horrified DeathGlare since he was trying to rescue Rachel from them, and he remains DefiantToTheEnd. Sweet Tooth then says he's dropping it into the water supply, ''unless'' Gotham citizens vote on Facebook to either order Sweet Tooth to put a bullet in Robin's brain or lower the Warhead into the water supply. It's their choice]].

* {{Tearjerker}}: The show's opening lines, which wouldn't be out of place in a dead-serious Batman musical.
-->One shot, two shots in the night and they're gone

* {{Wangst}}: As is to be expected from a Batman parody, Batman gets a good deal of it, especially before he meets Robin. Superman also gets quite a bit of it regarding his lack of popularity.

**

* NightmareFuel: Sweet Tooth is a walking moment of this with how he casually kills Penguin's bird lackey and sets his sights on hurting Robin, even wanting to murder him. The other villains are scared of him, and rightfully so since he's faster than he looks, with a bad sense of humor.
