YMMV: Jonny Quest
- Base Breaker: Though she only got to appear once, Jessie Bradshaw in the '80s series wasn't very liked by classic Quest fans for feeling like a shoehorned-in love interest for Jonny. Those who liked the character wished that she could appear more, although Jessie Bannon would more or less wind up filling the original Jessie's part.
- Ear Worm: That big band theme is as catchy today as it was in 1964.
- Ensemble Darkhorse: Jade, who only appears in two episodes, became very popular precisely because of how little we knew about her. She also offers a tantalizing glimpse at Race's past.
- Ethnic Scrappy: Charlie, the Chinese cook in "The Sea Haunt", comes uncomfortably close.
- Fair for Its Day: Nearly all the characters from more "exotic" countries - including villains - are little more than ethnic stereotypes of varying degrees. This includes one of the main characters, Hadji. This leads to Unfortunate Implications in the case of some of the Asian villains, who clearly show shades of Yellow Peril in their characterization.
- First Installment Wins
- So Bad, It's Good: The 1980's series is less coherent and more snark worthy than the original show.
- Values Dissonance: Multiple TOS episodes.
- What Do You Mean It's For Kids?: The TV movies. The original show... probably not. Remember that it aired on prime-time in the 1960s (although in later reruns it aired on Saturday mornings).
