Wow,that sentence 'There is no such thing as a perfect family' it blew my mind.How you always find the right senctence to go with the picture,just one small sentence But honestly I never really liked the fact that Aang was such a bad father.I don't mean bad,I mean he had to reive a whole culture but I don't think that he just ignored his other children.I mean that's Aang we're talking about,he would have found a way
But yes, I don't think he was a 'bad' father. But I think the whole Kataang family would have suffered under the pressure of Aang needing to restore his culture and also be the avatar. Probably not outwardly, but from the way Kya, Bumi, and Tenzin act in LoK, it's clear that there was certainly some emotional/psychological 'mishaps' during their youth. I would never imagine Aang or Katara doing those things intentionally though, it's just a matter of circumstance.
I can not see aang to be a bad father, I just...can't imagine the boy who cares about everything turning into that, they made it seem like he doesn't care about bumi and kya at all and that makes me really sad .
