Even as a kid I couldn't stand many of the cartoons. I found them plain and boring. I think that I would've preferred most of what comes on Adult Swim now, as opposed to what they had when I was a kid. And anime, I needed some ANIME as a kid!
Something that shows guns and blood, more realistic life or death situations than anvils dropped on heads, and characters who can actually die and stay dead. That is what I wanted. That's why I switched to more adult shows before 1st grade. The kid stuff was just too boring to me.
But, I was an odd kid, and stayed that way
