I've probably watched this show dozens of times. Every episode is new and different, it's rare that nickelodeon comes out with something so great. My favorite part of it is the character development. Also the animation gets better over time through out the show which is nice. There's a reason all these other people are rating it 10/10 stars. Also some of the episodes don't even have the fire nation in them. It's just the kids experience of taking down the fire nation. It has a great balance of humor, action, and drama. Not to mention the end is golden. I highly recommend you watch it. You won't regret it!
