I think if they hadn't made Korra and Mako start off as people who didn't get along but eventually came to respect each other, that would be fine. But suddenly there had to be romantic stuff. I almost think S1 would have been better if no one ever got together. I know it's hard to consider a show like that not having a romance sub-plot but it would have saved things I think and would have allowed the characters to grow before jumping into drama. *sigh*
