I miss cartoons with characters that have actual, well, character. You know, depth. Ones that have flaws other than complete and utter stupidity.
For example, let's compare two of the main characters from Recess with two of the main characters from Spongebob.
T.J. Detweiler and Ashley Spinelli are two characters from Recess. They are two of their gang of 5. T.J. is the leader, and he tends to be a troublemaker. But he's not without a conscience--he makes trouble for the enjoyment of childhood at its highest. For example, sneaking into a supply room in the school to retrieve all of the perfectly pristine kickballs, basketballs, and baseballs the school was hoarding to replace the ratty, worn-out ones the kids were forced to play with. What he does doesn't hurt anyone, it just gets on the nerves of the authorities.
And then there's Spinelli. Her first name is Ashley, and in Recess there are four other characters named Ashley, who are known simply as "The Ashleys" by everyone in school. The Ashleys are your typical, materialistic valley girls who are stuck-up brats and don't care who sees it. Spinelli, on the other hand, is the very definition of a tomboy. She defends those who are smaller than her on the playground from bullies, and doesn't mind getting into fisticuffs to do so. But she has a dilemma--her name is Ashley, so the school society tells her that she should be a girly girl. Spinelli even tries her hand at this in one episode, but decides eventually that she is the one who dictates who she is--no one else.
And then there's Spongebob Squarepants and Patrick Star. Spongebob is sort of an odd character--he's an adult, and has adult responsibilities, such as having a job and living on his own in a house. But his character is the very definition of childhood innocence. He is very diligent at his work and doesn't seem to have any financial troubles, but he often gets into other troubles. But they aren't adult problems, they're more kid problems. For example, there was an episode where he and his friend Patrick discovered curse words, and had to learn restraint with language.
And then there's his friend Patrick, who is Spongebob's age and presumably an adult as well. The difference between the two is that Patrick is not a functioning adult in any respect. He has no job, no responsibilities, and is constantly getting Spongebob into trouble.
As long as the show's been going on there has been very little character development, and most of the humor and conflicts rely completely on the childish innocence of Spongebob and Patrick. It's their complete ignorance of the world around them that gets them into trouble, and common sense that gets them out. No personal growth or discovery, no principles or core values that drive their actions. They aren't characters, they're archetypes. Archetypes of innocent kids, set loose into the adult world.
