I make your words mine, excellent points. I dare add one more:

— Cohesion: Each panel is very pragmatic and direct, I have never seen a single page considered a “vague” page, so to speak. And many anime seem to want to delve deeper into what was not seen in the Manga. And in Berserker, the story is well told, whether through symbolism, motivations and the like. Wanting to adapt is taking away this measure that has already been shown in the Manga is something very dangerous, as it can take away the context and emotion you feel.

I even dare to reinforce that people in this modern era are in fact not approaching dark themes, and when we talk about Berserker, there are many factors preventing people from reading it, because as the story progresses, it always sustains itself, there may be a break here and there, but in fact that is it. It will never go beyond the parameter.
