Is it simply parts of Avatar we dislike? Meaning that this is not limited too lines and scenes?

I dislike the ease Katara has to develope. She's been training for a few months to reach what takes years of intense training. Zuko's trained forever and a day, but Katara could easily best him since the North Pole, until the final episode of season two.

And I pretty much loathed any scene after Zuko's change in which he was unusually "peppy." The tone of his voice was just kinda.... CREEPY!

I cringed when I saw Zuko take Azula's side, but it's more realistic and better for the story this way. I mean, it'd be interesting to see Katara and Zuko hit it off, or at least see Zuko confront his sister and maybe actually put that technique Iroh taught him to work, but this way, it's better. I'm sure in the future he'll defect again and stand for what's right.

::)When in the Serpant's Pass, Ying is going to have a baby and Katata directs Aang to get some rags and he goes off into the bushes. Sorry if this does not seem very reasonable to go off on it, but...where is Aang going to find rags in the bushes?

Good one.
I also hate the fact that the mom is saying "I want the baby's name to be unique! I know, let's name her HOPE!".............right. So unique and original. I'm cringing from the unique-ness of it all. XD

*gasp* Katara, how could you post less that 300 characters?

Speaking of that, did you notice that Aang went to get rags and Sokka to get water, though Aang is a waterbender?

I also didn't like how, in the battle at the end of Crossroads, Zuko was even with Katara. That implies he's stronger than Azula, and that he's stronger than Aang, even though he has no skills and hasn't Fire-bent in a rather long amount of time. Meanwhile, Azula's a prodigy and constantly practices. Honestly, Zuko deserves to die at her hands.

"Looks like Long Feng is long gone!"

I know it's an intentionally bad joke on Sokka's part but egads is it bad. It makes me groan and I just can't stand it.

Okay, I'm not all that fond of the Zuko/Katara bonding moment in Crossroads of Destiny nor am I all that fond of when Zuko let his sister push his buttons yet again and sided with her. But, I was able to reconcile his betrayal because it is better for the story. His talk with Katara still wasn't all that great. Katara's all mad at him and the two sort of come to an understanding, but it still seemed awfully quick for her to consider using the Oasis Water on him. Honestly. She may have stopped hating him at that point, but it doesn't negate how he doggedly pursued them over the past several months or that he sort of lit Kyoshi Island on fire while trying to get Aang. Not hate him? Fine. Offer to heal his scar? Kinda odd.

Granted, if Katara was empathic enough to sense that a real act of kindness could turn him, it could be said that if she had healed his scar, he might have been less likely to side with his sister. But that's all hypothetical so it's a moot point.

Before I sign off, I'd like to point out that as a firebender, Zuko's improved greatly over the course of the series, and particularly towards the end of Season 2. Zuko is a hard worker, a guy who keeps trying even though he fails at it, like his mom said. While he couldn't firebend while in Ba Sing Se (except that he did to make Jin feel better...), he still had opprotunity to practice the actual motion. There was also plenty of opprotunity to practice before getting into Ba Sing Se.

Now when it comes to his fight with Katara, I think it should be kept in mind that his fight with Aang in that situation was kinda short, and Katara had already been fighting Little Miss Prodigy before dealing with Zuko. Katara's emotions probably also played a part in her performance. She was angrier with Zuko than anyone else at that moment, and it could very well have made her sloppy enough to just let Zuko's waterbending-esque firewhips be more effective.

What was the worst about the fight was Aang's performance. Out of anyone, he's the freaking Avatar and that kid got his butt handed to him. Zuko actually managed to come out of his fight with Aang looking better, and that's never happened before. Aang is technically more powerful than Azula, but he's never been able to beat her. His performance in that fight was shoddy and sloppy, possibly due to his fragile emotional state. But seriously, that was Aang's worst fight and I was far more embarrassed for him than I was for Katara duking it out with both siblings.

But, the overall point I would like to make is that talent doesn't account for everything. Azula is a prodigy, but that doesn't mean she's going to win forever. Her greatest problem in the end will be her arrogance, and I'm betting someday Zuko's gonna get smart. When he does get smart, he could beat her. Because it's easy enough to be diligent and practice all the time when you're so naturally gifted, but real strength comes from being diligent and practicing when it's difficult. That's where Zuko's strength lies.

And that's kinda where Aang stumbles. I hope to never see him fight like he did in Crossroads of Destiny ever again. It's embarrassing.
