I like Zutara, I like Kataang.
I just wished they'd made more of a background story for Maiko, then, who knows, I may even have liked that too! I would've liked to see more of Mai's personality through the show to see why it was that Zuko liked her. She didn't really seem to show any type of affection for anything until she started going out with Zuko, which I found a little odd.
They just seem to have Mai show up at the end randomly after not being mentioned at all for about six episodes.
