This is easily one of my all-time favorite shows. Silly adventures, amazing character development, just the most enthralling story, and colorful, dynamic animation. The talented group of writers, animators, and voice actors obviously put pieces of their soul into the show.
It's appropriate for children, teenagers, and adults.
The first few episodes are extremely silly. So if you feel like you're too much of a "grown-up" to sit through them, just skip to episode 4. I guarantee you'll want to go back and watch them once you become attached to these characters though. โค๏ธ
