Avatar is a very good show which I've seen at least 3 times. It's one of those shows that you watch as a kid and then come back to it as an adult and you still have fun. But it's not only good because of nostalgia, it has a very good plot, amazing written characters and it will surprise you many times throughout. Even though the main plotline is established this show has many tricks up it's sleeve. The characters in this show will make you attached to them, even the evil ones. It also looks amazing, every animation is showing the love that the creators have put in it. The music and animation make it so that every scene that is supposed to be funny is hilarious and every serious scene will have you sitting on the edge. It's also perfect for all ages and it teaches many good lessons. The ending is also perfect and will leave you satisfied. Overall I cannot recommend this one enough, if for some reason you haven't watched it yet DO IT NOW.
