I wish I could give this show more stars! It has an incredible story and plot, great animation, amazing dialogue and the best character evolution I've ever seen. Truly one of the classics as anyone will tell you. I think its allure comes from the attention to detail and how the show takes itself seriously.
It has a simple magic system that young children are able to grasp but one that can evolve as the show goes along, all while making for incredible action. It doesn't dumb anything down for kids and takes the darker themes of war and grief seriously, but doesn't go overly dark, and is often comedic.
It simply makes for a nice experience to watch and is enjoyed by many. I hope the live-action Netflix reboot does this justice, or at least portrays it better than the movie did. 10 stars all the way, I 100% recommend
