!! 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.
* TheWoobie: 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:
* 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...]]
* 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''.
