Pros:
-Azula vs Zuko
Hands down, this was my favorite fight in the entire finale. (Save Katara entering the fight.) I'll have to agree that I felt there was really no need to have the sacrifice and that part of the fight did make it a bit cliche` but at the same time, I do understand it: I think it was more to the point to show that Azula had no honor and just how much of a person Zuko has grown into: not so much a lame attempt (last ditch) at Zutara, but just because that's honestly the way Zuko is. Had that been anyone, I think he would have done the same thing: Zuko has honor that both Ozai and Azula completely lack.
But honestly, the music drove that fight home. It made the fight seem almost tragic and it really drove the emotion home: on the one hand, you desperately want Zuko to win but deep down, it's just pretty sad that this fight is even happening in the first place. You knew it was coming, but it was still just sad. It was probably my favorite piece of music that was played during the entire finale.
-The rest of the Fights
Pretty much, it was known that Aang would win because, well, duh. And while the playout WAS rather cliche`, I did like his solution to making Ozai no longer a threat and that's what I liked the most: while he had to use Avatar State to weaken Ozai down (Which in and of itself was awesome. It reminded me of a really cheap King of Fighters finale boss. ), he actually found a way that he could be satisified with and still save the world.
The White Lotus were just plain awesome.
Other than Azula/Zuko, watching Sokka and the rest of the gang take down the airships was kinda emotional. Esp. when Sokka got hurt and it looked like he would drop Toph. I still figured none of the Gaang would have died, but for a split second, it was sad to see that scene. Again, the music really moved the part.
-The Music
Rather beautiful and really helped to move a lot of the scenes.
-The Characters = Pretty Awesome
Just about everyone was on their best in this episode: the White Lotus rocked, Aang was emotional but kicked but (and still had a mini adventure, which I thought was a nice touch), Sokka and Toph where at their usual best, Ozai made one hell of a nice villian though. I'll admit, when his VA said "I'm still alive..." towards the end, completely with the scathing looking he gave Suki, it was actually kind of creepy. His overall nature throughout the show has been truly hate worthy and I think they wrote him very well. Besides, it takes a special kind of person to put Azula in her place with just a simple raise of his voice. XD
-Presentation/Scenes
There were just a lot of great (or even epic) scenes that happened during the finale that could touch a person's emotions:
1. Zuko and Iroh's reunion.
Overall, it was just very heart warming to see and long overdue.
2. Sokka holding Toph's hand; her slipping.
The way it was done was brilliant. The music, the slight slow down, Sokka's light joke as he desperately tried to hold on and Toph getting teary eyed as she realized she was about to fall, not to mention Sokka, with a hurt leg, had no way to get out of the way of the oncoming attack by Firenation soilders...had they wanted to do a death in this episode, had it been one of them, I think I actually would have cried.
3. Azula chained up.
I'll admit, I was in awe. Seeing a character like Azula, who you respectfully have to hate for her awesomeness as a fighter and brillance as a manipulator and cunning diva...to just see her slowly loose it throughout the show and to finally just go completely wild animal like, shooting fire from her mouth and sobbing...it was just amazing. That has got to be the one image that stuck with me from the finale. I actually felt sorry for her.
Just to name a few...
-Azula
Nuff Said...
-Humor
For this to be a serious event, I loved the humor that was introduced in this finale. Sokka and Toph were awesome as usual, the little exchange with the Firenation soliders on the airship was priceless, and Azula slowing loosing it was even funny in some places.
Cons:
-Katara
She just felt 'stuck in' in the finale to me. In the beginning, she seemed to have her usual 'Day in the Life' purpose as always, just like the rest of the characters. (Though I'll admit, forgiving Zuko aside, I thought she'd be a little more upset that he seemingly just attacked Aang for no reason...) But as the finale went on, it just seemed like they felt a need to stick her into the final fights somehow and to me, her involvement was just lackluster. I would have prefered that Zuko just finish his fight with his sister. Certainly, you can argue that Azula attacked Katara to show just how dishonorable she was, but I would have much rather seen Zuko persevere through the attack and still come out somehow beating Azula (not pulling WTF power out of his butt, but more like a 'David and Golith' concept) than Katara just coming into the fray, just to give her character something to do. I think in the end, the fight would have meant more. It would have been nice if they had left someone for Katara to contend with so she could have her own 1 on 1 or her own battle with someone else. Like if she'd met up with her father and the others and helped them kick butt, seeing another part of the ending war.
-Some events and storylines were wrapped up to quickly
I know it was just two hours, but honestly, I was a little disappointed at the time that was spent to certain events or what happened with certain characters. The White Lotus fight was wonderfully but felt short overall. I did love that Iroh took the very place where his son died and overall dreamed about taking, back for the Earth Kingdom: but since the place and the person taking it back over had so much more symbolism, I felt there should have been more time spent on it.
Mai and Ty Lee just felt rushed. After the pair went up against Azula and such, I just though the way they were just 'let out' and pretty much everything is happy go lucky was pretty lame: Zuko almost seemed like he forgot about Mai, being happy to see her and all. You think (considering how much effort they put into showing they liked one another) that him setting her free would have been one of the first things on his list. Or rather, given Mai's personality, I was actually surprised she didn't, along with Ty Lee, find a way to get free from prison to help everyone out heck, why no one even bother to look into helping them escape. (Now that was something Katara could have done: helped free the other prisoners with the help of her father and such.)
I'm aware that the Firenation might have been spread thin, but considering that they put up much more of an effort in previous battles (in this same season) I was a little surprised how this was done: the Dai Li? were just lamely brushed off, as were anyone that could have been a potiental threat anyone near the FNC where Azula was, pretty much purposely making the fight between her, Zuko and Katara that much more easier. I know it was done to show her 'madness' but it was also pretty darn convienant too. And the fact that they never show up anywhere else in the finale, like fighting the White Lotus and helping the Gaang's side after being dumped just seemed questionable.
-Unanswered Questions
I think I would have taken the "What happend to Zuko's Mother" unanswered question better had they not gone out of their way to dedicate a scene to Zuko asking. It's like seeing a piece of chocolate cake then someone telling you that your not allowed to eat it, even though you've been looking forward to it all day: it's just wrong. Though it definately gave off the vibe of "1 Hour Special to Come!"
Why exactly did Azula see her mother in the mirror? Was she actually there? Was the exchange a hint that Azula had something to do with whatever befell her mother and the exchange was a inside look to Azula own brief regret about the situation, for maybe not heeding her mother's teachings and warnings?
What actually happened to Azula? We can assume she was imprisoned, but then again, she also snapped pretty badly and was probably a handful.
Minor but I'd love to know: what exactly happened to Iroh's son and why wasn't he able to save him? And how did that lead him into the spritiual encountered and drastically changed his view on the war and Firenation's plans as a whole? (Honestly, they need to make a 'Secret of a Firenation' type of special, because a lot of stuff that was never answered had a lot to do with them.)
Who actually murdered Zuko's grandfather and how exactly did this come about? If Zuko's mother did it, was she tricked into it? Did he really plan to kill Zuko or maybe it was Azula and she believed it was Zuko instead? Did Ozai do it and she took the fall somehow?
Overall: 9.5/10
It really was one of the best finale's I've seen in a good long while for a show. It did leave things unanswered, which did suck, but overall, it was done beautifully.
