So now that everyone else is already done with it years ago, I finally watched Avatar: The Last Airbender. It definitely deserves the accolade it receives. I'm surprised Nickelodeon was able to create something of this caliber. The plot is simple, but the characters, humor, and action keep you entranced to the end, and the writers were able to produce surprises (particularly in the last two seasons) to keep you guessing. My only complaint is the final season, where I could tell they added elements at the last minute but pretended it was a thing all along, like the prince's girlfriend or the water bender's beef with her dad over him leaving. Still, these made the show more interesting so I don't mind, and the third season has possibly my favorite episode of the entire series (The Beach), so I'm willing to overlook it. Five stars.

Addendum: Okay, I have another complaint. I don't like how the prince's sister went out at the end. Like, she went nuts and paranoid for no reason at all, and it created an opening for her to be taken down. I know her two best friends betrayed her, but she seemed totally cool after that for a couple of episodes, and suddenly it got to her just in time for the final fight.
