!! YMMV entries for the WesternAnimation series, ''WesternAnimation/{{Underdog}}'':
* EarWorm: The Underdog Theme Song
--> When criminals in this world appear\\
And break the laws that they should fear\\
And rob from all who see or hear\\
The cry goes out both far and near\\
For Underdog (Underdog)\\
Underdog (Underdog)\\
Speed of lightning, roar of thunder\\
Fighting all who rob or plunder\\
Underdog...Underdog, Underdog
* FridgeBrilliance: In the "Commander [=McBragg=]" cartoons you can tell he's making up his stories because he looks the same in all his flashbacks as he does when he's telling his story. He would've been years younger had they'd really happened.
* FunnyAneurysmMoment: An ending to one story had Underdog humorously fly into the engine of a plane, with no real consequence. In ''WesternAnimation/TheIncredibles'' (in which coincidentally enough Live-Action Underdog's VA Jason Lee voiced the evil Syndrome), it's a ''[[Tearjerker/TheIncredibles very]]'' [[NightmareFuel/TheIncredibles different story.]]
* IronWoobie: Underdog's civilian incognito, Shoeshine Boy. He's [[NiceGuy extremely polite]] to everyone, even the villains, and gets constantly beat up on by Simon and Riff. But since he does not want to reveal [[PaperThinDisguise his true identity,]] he takes every hit. [[TheWoobie Awww...]]
!! For TheMovie:
* AwesomeMusic: [[https://www.youtube.com/watch?v=AlxyvZm_47A The remix]] of the classic theme heard in the intro is pretty badass.
* HarsherInHindsight: Since the film was released, the rights to the ''Underdog'' property have gone to rivals Creator/DreamWorksAnimation, and then to Creator/{{Universal}} Studios as well. This means that Disney now has to pay their biggest rival companies licensing fees, or ask for their permission, if they want to show the film again. Oops.
* HilariousInHindsight: This wouldn't be the last time Creator/PeterDinklage went by the name of [[Series/SesameStreet Simon]].
** Creator/AmyAdams voices Polly, the Lois Lane to Underdog's Superman. [[Film/ManOfSteel Then in 2013...]]
* HoYay: ''"That time when I met that cute poodle and.. it turned out to be a guy."''
* SoOkayItsAverage: Really it's a kids movie and a live action adaptation at that. Only reason it bombed was basic lack of interest due to these factors. On its own, it's an alright little romp with a few chuckles. And at the least it keeps the basic gist of the cartoon better than, say, ''Film/InspectorGadget'' (so Disney and Spyglass, the successor to Caravan, which co-produced the ''IG'' film ''had'' learned their lesson from that disaster).
