I really like the fact that one of the characters in "The Lego Movie" got her own show, so "Unikitty!" would be my favorite cartoon show XD

Gosh time flies when you're in uni, sorry for not replying earlier.
Oftentimes when i'm stumped for what to watch, I just look through Pan Pizzas videos. Sometimes he gives out some very good recomendations. For example, now I've been meaning to get into Final Space. It looks nicely animated and i don't know much about the plot. Hopefully I'll like it!
Short films from animation students are so good. There is this one from a french school that always stuck on my mind which was basically birds gijinkas being flirty with each other.
I was curious about Final Space too. Who is Pan Pizza?

I like Steven Universe but my son really enjoys Super Monsters and its not a bad show :)
Not sure how active this thread is anymore but Avatar: The Last Airbender remains to this day my number favorite animated series. The art, detail to the world, plot, character development and thematic elements are all absolutely amazing! Haven't been able to really get into Korra, but I'm still working on that :) Other favorites are the original Teen Titans series (it also developed extremely well) and Danny Phantom (which started off episodic, which makes sense considering the targeted age demographic but then I found had quite a bit of solid plot and character development and the series progressed up until the finale).
Currently another absolutely fantastic series in Miraculous Ladybug and Cat Noir. The pace at which new episodes are coming out is extremely frustrating, and the show is very episodic in nature since it's targeted to younger kids, but the production value of the show is extremely high and I would say it's incredibly worth it to watch.
My favorites as a kid were Tenchi Muyo, Foster's Home for Imaginary Friends, Codename Kids Next Door, Pokemon and Yugioh.
Unfortunately, there aren't any cartoons I watch now. Not many good ones on now that I'm in my Mid-20s. lol
