Well, first, the production values are as amazing as the first episode's. The art is excellent, the animation is pretty fluid, especially some of the more subtle gestures of the characters while they're in conversation. Nobody seems to just be standing motionless for no apparent reason. The coloring is such that it looks fairly natural for a show about colorful giant robots. In other words, the shading isn't off and nothing looks too shiny and fake. The music is atmospheric.
