The core of excellent children's cartoons is childlike innocence and values, and the picture is the second.
Let's talk about bears. You can't see innocence in it, what you see is retarded and messy values.
A big problem is the level of domestic comic writers, of course, not only comics but also film and television dramas. I think there is a problem with the values of skills or with investors and decision makers. People who are suitable for younger age are often equated with mental retardation.
In my opinion, Tu Tu with Big Ears is one of the few good works, but some plots in the later period are actually off course.
