I don't know what everyone is talking about tbh. I finally got to watch the last couple of episodes of legend of Korra today, and I am really not sure if I watched a different last episode than everyone else here. But holding hands doesn't constitute being a lesbian lol. I mean girls do this kind of thing all the time people, men shake hands, bumb fists, give each other the fingers, that how men roll. Girls kiss each other(not sexually) hug,cuddle,hold hands, that is how they roll. So for me I see no reason to believe that Korra is batting for the other team so to speak. I think it just come down to narrow minds and how you interpret the ending.
On another note, it comes no way near ATLA. It was ok, but damn, it could have been much better. Even the minor battles in ATLA were awesome compared to the battles in this. But oh well thats a different story lol
