I know that a lack of character development is one of the tackiest, most misused complaints thrown at an anime, but when the characters are this shallow, and none of the side stories leave any kind of impact on a pair of characters consisting of a child and a person slowly gaining back and developing his humanity, I'm left begging for something, anything to change before completely checking out by episode 18.
I’m barely gonna touch on the side characters, even Hyakkimaru’s family and the people that serve them, as they’re mostly just boring character archetypes like the suffering mom, the warlord who cares about his nation almost as much as he does his reign over them, and the edgy, jealous younger brother who constantly tries to prove himself in order to not feel overshadowed. There’s also the wise, badass old man with some sense of humor. To be fair, the show does a fine enough job not screwing these characters up with dumb decision-making or erratic personality shifts, at least for the most part. It’s just that it’s hard to care about characters who are on autopilot, just as it’s hard to care about our main characters. There is one exception to the lack of character shifts, that being when in episode 12 Hyakkimaru’s brother suddenly goes from someone torn on the moral quandary of his brother’s life vs the nation that thrived off his unwilling sacrifice, to someone hell-bent on killing him after failing to end a deal between the demons who cursed Hyakkimaru, and his father who made a pact with them for the sake of power and a prosperous nation. Apart from that moment, you can predict every character’s archetype and actions the moment you see them. The only recurring character with anything to him is the guy that took care of Hyakkimaru for most of his life: Jukai. He has a genuinely horrific backstory that informs his somber nature and constant need to seek out ways for his craft to be used in ways that compliment life, something he feels he’s stuck with due to not having the right to die like everyone around him does.
At this point, I’ll just list a few other issues with the writing. The characters arbitrarily doing stupid things for the sake of the plot in the second half, such as Dororo randomly falling for a trap door in a seemingly abandoned shack in episode 15 despite her being a trickster character who would never be this gullible, or Hyakkimaru not even thinking to chisel the rock trapping Dororo’s arm to free her as she’s drowning in episode 20.
