yeah, I saw the trailer. It really felt more like a japanese soap more than an adaptation of the manga, seemed all loud, punchy and emotional like most J-Dramas. Felt like a direct opposite of the approach in the manga being silent, sombre and introspective. In my head, a proper live action adaptation would use a lot less words and more silence & negative space for the audience to fill in with their imagination.
I don't think animation would bring that much added value aside from the extra control of the pacing though.
