I did not expect this but Nadia episode 13 was almost insane animation wise. Even more surprising since the episode is so sloppily put together (poor transitions, layers and cells move in the frame almost every time there's a prolonged shot, or cells outright disappearing at one point towards the end, and a lot, and I mean a LOT of recycled material). It reminded me of Birth in many ways. Very snappy animation, with quick movements and almost constant motion. And this breathes a lot of life into a pretty wacky scenario otherwise. Very cartoonish, and very fun art overall. Oh and it has a lot of background animation, like every third scene or so has background animation. Many shots feature pretty simplistic animation but it's wacky in a cool way.
At the surface it kinda feels cheap as hell but so creative it left me jaw-dropped and gasping by the end. The storyboard is great, the train and Gargoyle robot chase scenes were so good, with a lot of pretty insignificant but quirky details that spice it all up so well. Like bulling a giant boulder outta nowhere (or hammer space, however you choose to call it) - this kind of stuff. Masayuki took some risks with this I think, because the style is pretty different from the other episodes.
It has to be one of the best bottle episodes I have ever seen. Definitely need to look up who worked in this episode. I'm watching that THORA rip that uses chapters so the ending is always the same, any tips where I can find the staff other than ANN which is incomplete?
