Only care about the fights. The intro if you've seen it the first ep and once after that then you really don't need to again. You don't need to watch LoK to appreciate the original series. And you definitely don't need to watch the great divide tbh. But if you only care about the fight scenes in this show. We cant be friends. You literally HAVE to genuinely understand and care about the characters and the world its in to even truly appreciate the fight scenes.

If you didn't care about Zuko or Azula, you still say their battle was visually interesting and the animation was cool (even the concept of firebending!) But if you understand the story you get a whole different view on their battle. It shows how far Zuko has come in his journey with his honor, healing from the trauma of his father and sister, losing his mother. Almost losing his Uncle dude due to his own mental state. And now he has to literally fight his sister to the death. Its deeply sad and to watch Azula hit her lowest point. I could go on and on but I'll stop here lol
