Great news, although I'm really not thrilled about books not being seasons. Especially if there's going to be a big wait between books. That's a nitpick though.
to be honest i wouldve preferred for this to be a mini series. the only thing i didnt like about it was that there were still unanswered questions from part 1 and that everything was half assed at the end. first he tells asami he loves her and tells korra he loves her? korra just automatically becomes a master when aang gives her her bending back? and alot of people didnt have as much character development as they should have. but other than the ending and the disappointing "big fight" towards the end, this was all inall a great series. i just hope that this forced second season doesnt ruin it or at least ties up some loose ends
I legitimately don't understand why you're against it continuing if you thought the ending sucked but the rest was great. Wouldn't that entail you to want another book/season so that they can add the character development, and produce a story that has a satisfying beginning, middle, & end? I don't know, maybe that's just me.
