No true fight can be won without sacrifices. A victory without sacrifices always feels cheap and unrealistic. The ending of Endgame displays such cheapness. Giving Chief Beifong back her bending was nice, but it took away from the heroic sacrifice that she had made to protect Tenzin and his family from Amon's forces. Aang showing Avatar Korra how restore bending all but ruined that last episode for me and damaged my view of the entire series. I can only give it a 3/5.
