I can handle your thoughts if you like any of these shows I mentioned here.
Family Guy
It seems today, that all I see is unfunny humor and offensive jokes.
I tried watching some episodes of the show to understand why people like it so much...and failed. There are too many unfunny jokes about rape, abuse, incest, etc. that prevented me from actually getting into the show at all...and also, I hate how Meg keeps getting ignored by Peter a lot! And I also think that Peter is a slight ripoff of Homer Simpson, whose show is way better...
South Park
Another overrated show I can't stand...also, the line, "Oh my god, they killed Kenny!", is never funny to me, I don't understand why they have to keep killing off the same main character, and bring him back not long after! And there are too many unfunny jokes regarding rape, abuse, incest, etc., like Family Guy.
Happy Tree Friends
It's a cartoon about cutesy animals killing each other, rinse and repeat, there's never anything funny about that.
Steven Universe
Another show I couldn't get into, it's way too overhyped.
Miracle Star
It is a cartoon that straight-up ripped off one of my favorite shows!
The Samsonadzes
It is also another ripoff of one of my favorite shows, as well...
Cocomelon
I don't hate this one as much as I hate some of the others...but I keep seeing merchandise of this thing everywhere, and it made me dislike this lame web series!
Baby Shark's Big Show
Why make a show that's already based on a popular kids song, that doesn't make any sense...
Pickle and Peanut
Why does it even exist...the character designs are ugly, the show looks more like something that aired on Adult Swim.
iCarly (2021)
It's a bad revival of one of my favorite Nickcoms, it tries too hard to be hip and cool with the kids...which I absolutely despise! And also, there's swearing present that's out of place for something Nickelodeon related.
Bluey
Also another overrated show, I'm tired of constantly seeing merchandise for this show in most stores everywhere.
My Little Pony: Friendship is Magic
I used to watch this show when I was a kid, but...those freaking bronies everywhere and everything pony-related taking over the Internet, and also real life, ruined the show for me forever!
The Powerpuff Girls Z
It tries too hard to be an anime adaptation of one of my favorite shows...but it failed badly! It's bland, and I keep forgetting about it. There are so many pointless changes in the anime, compared to the original 1998 cartoon.
The girls in the anime are not sisters, Blossom and Buttercup have different siblings, Bubbles is an only child, and they're not even related to the Professor himself.
They changed the gender of one of the members of the Gangreen gang, Snake, into a girl named Ivy, the mayor has a brother who is the school principal, and the Amoeba Boys have a female member...
Drawn Together
I tried to get into this one, I thought it was going to be a fun watch, it ended up being way too raunchy and unfunny. One of the characters in the first episode even had an on-screen erection, although censored...and I was already like, "nope", and stopped watching it.
Rick and Morty
It is a shameless ripoff of Back to the Future, I tried so hard to like the show, as I am a fan of the Back to the Future film trilogy. Yeah...nope.
Clone High
I don't think it's a very good idea to create a cartoon about historical figures going to high school together in my opinion. The show is very boring, and very unfunny.
The Brady Bunch
My mom made me watch this show with her, because she loved this show from her childhood, but I really don't like it at all...the characters all have no personality whatsoever, they are emotionless like robots! Also, there is VERY little to almost no humor at all present in this boring and bland series...
I Love Lucy was WAY more iconic, better and funnier than this!
Little House on the Prairie
My mom also made me watch this with her, because it is her absolute favorite show from her childhood. I don't know which I hate more, this, or The Brady Bunch! I do like the idea of a show taking place in the 1800-somethings, because I love historical and ranch/country/western themes, but that's not saying much. To me, this show has way too much unnecessary drama, to the point of being overly dramatic,.
Velma (2023)
My god, man, don't even get me started with this one! You can't possibly list your least favorite shows without mentioning this garbage!
Regular Show
I'm sorry, but you call this a Cartoon Network original! It sure feels a lot like Cartoon Network is basically trying to promote Adult Swim to teenagers, or something...
And also, most anime series and object shows.
A LOT of anime shows share the same art style with every character, left and right, to the point of being copy-and-pasted! Which is a common problem I already have with cartoons with characters with the same copy-and-pasted faces, like South Park and Family Guy.
