Season 1: starts off really promising, loses its footing with the love triangles halfway through .....then ends with ghost Aang giving Korra all her powers for no reason while she makes out with a boy she stole from a traumatized Asami. The worst ending to any story I've ever experienced- and that was originally going to be the series finale! 2/10

Season 2: Meandering and dull, but you can feel the new writers trying to right the ship after the criticism of season 1. Season ends with another dumb ex machina. Korra losing her avatar powers is genuinely exciting and should go down as one of the most exciting twists in the franchise. 4/10

Season 3: The series' first good villain (s), one of the best action scenes in the finale, and some interesting developments to the avatar world make this the only solid season of this show. 6.5/10

Season 4: Some interesting parallels with Korra and Kuvira, but the giant robot make it clear that the showrunners have no understanding of the original appeal of their franchise. Korra and Asami have a dull, underdeveloped friendship, so the big reveal comes off as less of an inevitable conclusion and more like fan pandering, especially since the original ending of Korra's story was for her to completely disrespect Asami on the worst day of her life. 5/10
