I think one of the possible roots of the problem people have with Korrasami is that Asami didn't get as much screen time as Korra, Bolin, and Mako.
She was barely there in Book Two, and while she had a much better showing in Books One and Three, Book Four didn't give her much to do either. More than Book Two, but not that much. If only that damn clip show didn't happen. Also, would have been nice to have more episodes per book too. I'm still happy with how it worked out, though
