I love cartoons because they can be extremely simple, but still enjoyable. However, at the same time they can be as complex as you want them to be. You can read inbetween the lines all you want and always imagine that there's more to them. I guees that's why there is so much fanfiction based around cartoons.
I also love them because they are escape. Life can be kicking me when I'm down, but cartoons are always there to entertain. Also, in the cartoon world, good always wins.
What I don't like about them: Some of the best ones get cancelled for really stupid reasons. May that never happen to Foster's.
