Warning: Contains spoilers for Bleach: Thousand-Year Blood War part 3, episode #8.CGI in anime is always a divisive issue, and Bleach: Thousand-Year Blood War is no exception. While it’s fortunately been used sparingly, every instance has invoked the same common criticisms of poor visuals and animations, most notably with Komamura’s Bankai in part 2 and the Hollows from the series premiere, and they especially stand out when contrasted with the largely great 2D animation in most episodes.
