History YMMV / HeidisSong

* SugarWiki/HeReallyCanAct: While no one can deny Music/SammyDavisJr's skill as a performer, he was usually known for being smooth and charismatic. Here, he plays a villain, and you can tell that he's ''really'' into it. The way Head Ratte's voice [[EvilSoundsRaspy rasps]] in certain lines (most notably, "Unless your style / is so vile / you can cause a sensation) is just incredibly well done. His performance manages to be both sinister and still, if oddly, charming at the same time.

* SugarWiki/HeReallyCanAct: While no one can deny Music/SammyDavisJr's skill as a performer, he was usually known as a charismatic showman. Here, he plays a villain, and you can tell that he's ''really'' into it. The way Head Ratte's voice [[EvilSoundsRaspy rasps]] in certain lines (most notably, "Unless your style / is so vile / you can cause a sensation) is just incredibly well done and ''very'' sinister. Despite that, Davis Jr. still brings a lot of charisma to the character, making the Head Ratte a very enjoyable antagonist.

** The ''[[VillainSong She's a Nothing]]'' song sequence. The song is Rottenheimer and Sebastian bullying Heidi by telling her she's small and worthless in various creative ways (or at least, Rottenheimer is creative. Sebastian just keeps repeating what she says.) The scene features a creepy DisneyAcidSequence where the two villains (and Schnoodle) morph into monstrous versions of themselves. Rottenheimer's monster form resembles a WickedWitch. To make things worse, her voice gains an echo effect when she turns monstrous. The music itself uses very eerie instruments (and the scene, eerie sound effects towards the end) that make the song spine-chilling to listen to.
