Korra is suffering from an annoying protagonist (Then again aang was pretty annoying too and toke some time to like) but the thing is the rest of team avatar made up for it. Katara, sokka, Toph and later zuko they were all great, plus add in azula and you have a magnificent villain with one of the greatest downfalls ever. But team avatar 2.0 has mako who is just a jerk 24/7 and stiff, Bolin who is admirable and fun but feels like a water down version of sokka and then asami who they haven't dug deep enough into her character to make me like her, but I feel she has the most potential. Other than that its still a great show, in fact I like Tenzin and many of the story archs, not as good as the first but I guess that's okay. Also as was I, I was binge watching the show one summer and it was great I hate how netflix contracts suddenly end.
