That whole Korra X Asami thing was kind of forced into the ending which I didn't really like, they should of built the relationship first instead of just forcing it in that's one of the reasons lots of people didn't like it. If people want same-sex couples in TV shows then learn to do it properly and not just do it to prove a radicle point.
(And don't tell me that their relationship was built up because it wasn't, they had nothing more then a normal girl-girl friendship beforehand.)
