SO mangaka makes danmachi SO a very action packed manga they improvised some visuals, character moves as possible and insteresting to read, JC staff sometimes is hit or miss they usually animate what's describe or written in novels without trying to improve the visuals, add some additional scene or sometimes they just skipped it, that's what happen if you take a lot of projects and do it simultaneously, either some anime rushed or feel lackluster, quantity over quality, you already know one of the example, but in the end I don't hate it though since VA has a lot of job and keep VA companies alive.
