This is a phrase in my homeland. In this context, it can be used approximately like this: the newer the year of a Western cartoon, the fewer normal examples there are. You can count the good ones by the fingers of one hand. And I am not even talking about the depth of the plot, but rather about the production inside it, graphics, dialogues, or motivation of the characters. I am also horrified by the fact that there are so many people who defend such works. If you are not particularly picky about the quality of a movie or cartoon and you are satisfied with "chewing gum for the brain" - please, this may occupy you and you may even like it, but for others I do not recommend it at all.
