I don't think I'm ever going to bed tonight.
I wasn'treally moved by Korra's paralysis (legs), but probably because I know that they aren't going to make a tv show about martial arts were the protagonist is always in a wheel chair. Too cynical I guess to fall for that little emotional schtick with the tear at the end.
I think they're trying to do what they couldn't do for the Season 1 finale due to the time constraints.
