The whole finale was awesome, but my favorite parts were

-Aang vs Fire- oh sorry! I mean, Phoenix King Ozai (grabs his beard XD that was pricless)

-Azula vs Zuko & Katara

-The "Beach Party!"

-Sokka in Appa's mouth and his description about Aang's battle

-Zuko's coronation and the ending scene

Actually, I just watched the finale today for the first time.
AMAZING!!!

I loved the animation, and balance between all the different genres such as comedy, action, and romance.

Talking about favorite parts, I really liked one of the first scenes with Zuko chasing Aang around. That'd be one.

The second time I watched (this time alone, so I couldn't embarass myself farther), the Iroh and Zuko reunion had me close to bawling. I swear, every single time I see Zuko start to get seriously emotional, I tear up. So, to see him drip many tears for more than 30 seconds made my frikkin' viewing life- and cost me my strength of resisting.

Totally loved when Aang got all cosmic with the Avatar State. It was an amazing fight!

Favorite of all: Zuko VS Azula Agni Kai.
It was sad really. The music may have not been quick to beat like Aang and Ozai's battle was, however, it fit perfectly and added so much tension- like you knew this was the final stand, the final fight between two waring siblings, and that something was gonna happen. The whole thing was very emotional, and very depressing for Azula in the end. Who used to be a steady and talented young firebender turned into a paranoid, fearful, and breaking girl. Usely, when I see villians go into mental breakdowns, it's kinda cheesey. This- anything but! I thought the writing for this was played out nicely. And Grey Delisle did an awesome job!!!

When Yoph and Sokka almost died.......i wanted someone to die, but no one did

Most Emotional Part = Zuko reconciling with Iroh
Exciting Part = Aang (in Avatar State) chasing Ozai
Best part of all = Azula and Zuko Fight (I like it so much I viewed it in my iPod for a hundred times; the faded sound and the dramatic music combined made it the best Fight in the Finale).

Besides the fight scene, I liked the return of Aang.

Watching him take down the Fire Lord's ship and then stare him down with a challenge, which then the Fire Lord prepared for battle, was pretty cool.

I wish it would have covered more, but it still was sweet.

Zuko/Azula Agni Kai. I loved the scene with Azula chained and crying and screaming. It was well done and so demented.

I liked the whole thing my favorite party Aang vs the Fire Lord. My most feared part, Azula screaming and crying. My least favorite part, Aang's final costume.

I found it weird how every fire bender decided to start flying around on fire.

Every? Try three, and only during the comet.

i would have to say one of my fav parts was when Aang was stressing about killing the fire lord or not and he flipped out at Katara. throughout the show she is often made out to be the one who has all the right ideas and knows what the "right thing" to do would be, so it was nice to see that turn around. and with kinda that same idea, i liked how they made Azula lose it. also throughout the show they have made her the villainwho makes all the right moves and almost never slips up, who is always one step ahead, its always entertaining to see a strong Villain crack.

Azula vs Zuko and when Ozai was beating Aang
