If the first half of the season was impressive to say the least, the second half is mindblowing.
It’s an incredible muscle flex.
Basic principles of animation is that frames are expensive, backgrounds are cheap. You can have a single background for thousands of frames. That’s why you generally avoid “camera movement” in animation: it moves the background.
And that’s exactly what they’re doing here. They rotate the camera, in a rather mundane scenes, or show scenes from different angles. Something common to movies, although still not cheap. And extremely rare for anime.
What else did they do? Unique ending for every episode. Again, that’s something you just don’t do. Animation is expensive! So, you draw one outro, and use it for 6, 12, maybe even 24 episodes. But those crazy bastards decided otherwise.
