Woot?I didn't like some of the CGI in this episode - particularly some bits in the Infinity Castle that looked like skyscrapers. It looks like they got regular skylines and just tweaked them a bit. It looked quite unnatural.
Not only do I understand what exactly you are refering to (even after rewatching it after reading it), nor do I understand what a more "natural" look would be like?
Welp.
In my opinion the first ~16:30 minutes were absolutely stellar in terms of animation, both quality wise and general looks.
I honestly can't remember seeing anything better - some things were equally good, but better? Not sure.
It wasn't repetitive - you got to feel that even this infinity castle has different "zones" yet at the same time you'd be lost at every corner - that's quite difficult to achieve imho.
The sound was amazing as well. From 1:36 - 3:00 gave me chills everywhere, and what came after that was just awesome.
Pretty sure that scene is reward worthy. It made the villain look and feel so untouchable without actually using anything but scenery.
