I’m not ani-Kataang as a pairing. I’m fine with Katara and Aang getting married and having many bending babies and living happily until the of his days. I don’t actively ship it, but I’m not a Kataang or Kataang fan hater, either.
However, in my subjective opinion, I did have a problem with the complete lack of chemistry in the show and then expecting us to buy them getting together in the end. Also, 12-year-old kids should not be making out. Blech.
Those are the only real opinions I have about Kataang, except that Goatee-Aang is pretty cute.
