Those are precisely the kind of things I think Netflix and Studio SARU went a little too far in Crybaby. When shock value has more worth to you as a storyteller than narrative coherence, then you're doing something wrong.
I can see they tried to pull a Snyder's Doctor Manhattan with Jinmen but, as you never really get in touch with Akira's parents, you never get to know what might have turned Akira's father into such an egotistical, cruel beast (by Crybaby's internal logic, at least). In Devilman you don't have to care about Jinmen's motivations because he's just there and Nagai quickly establishes he's one of the most sadistic, devious demons of Hell.
Netflix has been careful about doing 13-episode seasons, but I think Crybaby would have greatly benefited from this. I guess we'll have to wait and see how they adapt Devil Lady, if rumours are to be believed 🤔
