when I was a kid, the Warner Brothers "Looney Tunes" Cartoons re in their golden years. The comedy was rather sophisticated so the kids had to think upwardly to "get it". The art and voices were excellnt and the stories were often a bit over kids heds , so they loved em.
Then, when the sixyies and later decades arrived, cartoons were amazingly "dumbed down" with the exception of a few erly versions of "Rocky the Flying Squirre" or "Dudley Do-Right".
A far as cartoons in Wurope and elsewhere, Ive been pretty critical of Manga style cartoons. I find them very bland with low quality art and silly childish story lines. EU cartoons, Im not aware of any other than the later claymation work of "Wallace and Grommet" Which were rather high quality.
The best though were still the Loony Tunes of the late WWII through the mid 1960,s THEN EVERYTHING was later designed for the 5year old mind.
In my estimation all the really good stuff was merely action /comedy, with the evil biy of VIOLENCE that made all cartoons the target for helicopter parents and "ComicCode Regulations" turning good fun into mindless crap.
I havent seen any really good cartoons of the goldn yers . The fully adult cartoons (like SOuth Park) totally ignore a kids market and are mostly light porn.
I suppose the "Simpsons" which began in the late 1980's as a fill-in for a Brit comedienne remains one of the very few well-done action comedy cartoons that has flourished into the present over regulated society.
