I am 18, so no, i don't. I hate 18 year olds and shows that feature them. Most of my favorite cartoons feature kids of around 8-18 years of age. Phineas and Ferb, Daria, etc. I never much cared for adult characters (with some exceptions) as i find adults overly utilitarian and dull. Whereas a kid, like a villain, has more freedom of character and what they can do, whereas adults have jobs and are all pretty much the same person with personality quirks added for humour. Kids are better than adults in animation imo for not just this reason but because they are more mature than adults and more civilized overall, less concerned with dating, sex, alcohol, work, money strife etc, and thus more civilized and normal on the whole. ed, Edd n Eddy for instance are good examples of characters that couldn't exist as adults. Phineas and Ferb could never do the stuff they do as anyone over school age.
