The fact that they tried to pull the "actually some Martians are good people and this is a very nuanced conflict" after the first episode literally ends with them all landing in the middle of a bunch of earth cities with no care for the civilians there and literally incinerating people with the shockwave from their ships landing, is still one of the most embarrassing things I have ever seen in a mecha anime. Fucking mustache twirling villains that act like royalty while eating TV dinners.
