I've come to the conclusion that you're too jaded about life when you refuse to watch cartoons for the sole reason that they are cartoons, and cartoons are for kids. If there is no remnant of a kid in any of us, then we can no longer experience innocent joy, laughter, and happiness. Instead, we have only cynicism, skepticism, and anger. That, my friend, is being jaded.
Hogwash to those who say they don't watch cartoons because cartoons are not intellectual enough. Watching cartoons does nothing to take away from one's intellectual capability. If it did, then your intellectual capacity is truly low. That's like saying you're too manly to cry; it takes a real man to cry. :p
