Top 10 Things that Make a Cartoon Episode Bad

For me, the South Park episode "Breast Cancer Show Ever" comes to mind.

Pretty much a lot of Modern Family Guy or SpongeBob episodes that just want to bee disturbing or disgusting just for the sake of it and goes way overboard with it and to a lesser extent "Ren Seeks Help"

My favorite example would be Family Guy,Sanjay and Craig, and especially Breadwinners. Looking at what kids of today find funny I worry for the next gneration, growing up doing stupid things and having no good sense of humor

ONE THING: Grossology.

This definitely should be number one. Family Guy does this crap so much and it's one of the main reasons why I hate that show

I just dislike it when people make jokes out of serious things.

I'm looking at your Family Guy and Amazing World of Gumball that both tackled a similar serious subject matter and failed horribly at it which is abusive relationships

Pretty much every Squidward torture porn in a nutshell where an episode punishes or tortures a character for literally no good reason.

Yeah, talk about it... - Squidward Tentacles

This happens to Meg especially.

This happened in pre-movie SpongeBob too. “Jellyfishing.”

Too many episodes do this they have a really good idea but end up squandering any potential the episode could have had a few examples The Loud House's One of the Boys, and "Oral Report" from SpongeBob Squarepants and one from Courage the Cowardly Dog "Ball of Revenge" - egnomac

Those episodes where one character acts really horribly towards other characters in an episode and faces no punishment for their actions such examples "Everyone Knows It's Bendy" and every Patrick's a prick episode. - egnomac

One example is the Fairly Odd parents episode "It's a Wishful Life" where Timmy does good deeds for everyone only for everyone to be incredibly spiteful and ungrateful for what he does that he wishes that he was never born only for Jorgen to happily show him that everyone is much happier that he never existed. - egnomac

Even if an episode is terrible it can still be saved with a good ending however a bad ending can really kill an episode like for example having a character goes through so much pain and suffering and you think the episode is finally going to have mercy on them only for them to get screwed over again in the end or have an ending that make the episode feel entirely pointless. - egnomac

Episodes where a character acts like the complete opposite of how they would normally act - egnomac

Modern Spongebob - Dustbunnie

Chloe Carmichael completely ruined FOP.

Chloe. Carmichael. enough. Said.

While I do agree that Chloe wasn’t a good character, her addition kind of makes sense on a logistical standpoint. The Fairy Counsel banned fairy babies (meaning no new fairies) and any new godkids had to share fairies with existing godkids.
However, that doesn’t justify her being a one dimensional character. Still, I know what I’m saying when I say I’d rather have Chloe over Sparky any day.

Perfect example Lisa Goes Gaga from the Simpsons. - egnomac

Just an example "Demolition Doofus" where Mrs. Puff tries to murder SpaongeBob after he cripples her then doesn't show even the slightest bit of remorse. - egnomac

Two episodes from South Park that come to mind is Pip and A Million Little Fibers both star a secondary character that aren't capable of carrying an entire episode.

I loved that “My Leg” episode :(

So? This gives us backstory to the character and why they did what they did.

An Obvious Example is The Pre-Season 2 Lord Cucuface From Madeline.
