YMMV: Fanboy and Chum Chum

  • Alas, Poor Scrappy: Wether you love or hate the duo, the former's treatment in the second half of "Precious Pig" where he is shunned and banished to the back of the classroom after he is accused of hurting Precious; given he attempted and succeeded to teach him karate.
  • Alternate Character Interpretation: Sigmund's nervous "Oh? Friends? Ahaha! Such happy for you!" was a brief unmasking of his haughty facade. Perhaps he was jealous of Kyle for having friends, which he—possibly—does not have (it would make sense, considering how arrogant he is) and decided to invite himself to the dinner at Kyle's house so he could humiliate Kyle (which he achieved, since Kyle admitted he was worse than him in the end) to make himself feel better? The aesop of the episode seems to support that theory—after Sigmund left, Kyle was in a defeated state, until Fanboy and Chum Chum assured him that he still has his friends, to which the reply was "Yes... I suppose I am the winner after all".
  • Ass Pull: The Dollarnator at the end of "Dollar Day".
  • Base Breaker:
    • The titular characters have their fans, however they're also the main reasons why some people can't stand this show.
    • Yo is either cute or annoying, depending on whom you may ask.
  • Big Lipped Alligator Series
  • Critical Dissonance: Some people and reviews have given the show extreme backlash. That being said, the show won five Emmys (the most any Nicktoon has been awarded tied only with El Tigre), and it's premiere episode gained almost six million viewers.
  • Ear Worm: "Here we go, 'cause we're Fanboy Chum Chum! A little cuckoo Fanboy Chum Chum!".
  • Ensemble Darkhorse: Kyle. A self-aware Snark Knight magician with a backstory similar to that of Harry Potter? Yes, please.
    • Sigmund gathered a large fanbase long before he even made an appearance in the show.
  • Hilarious in Hindsight: A Frederator-made Nicktoon that features a tall youth and a shorter one with dark hair who tend to annoy an outsider with unusual powers trying to fit in with normal kids and one of them is british; sound familiar?
    • Heck, Kyle even kinda looks like a Rule 63 version of !Human Jenny with the red hair and freckles.
  • Idiot Plot: "The Last Strawberry Fun Finger". Not one person considers just splitting the Strawberry Fun Finger in half until the end.
    • In "Saving Private Chum Chum" Mr. Mufflin apparently forgets who Chum Chum is and mistakes him for a toy.
  • Nightmare Fuel: "Fangboy": Suddenly Fanboy doesn't look so cute...
  • Tastes Like Diabetes: Yo is a living example of this.
    "Doesn't Prank Day make you think of rainbows and puppies and Chum Chum?!"
  • Uncanny Valley: Everyone has their moments where they look.... off. Closeups especially.
