I found it best to enjoy ACCA by disconnecting from the manifest impossibilities of their world, such as massive government monopolies doing anything right. Mussolini making trains run on time is a myth after all. But then it's a myth people want to believe in. ACCA is like that too, a creature of fiction into which one indulges. As myths go, this is a pleasant one.
Characters made the anime as usual. The little sister was just enough of a naive airhead, but not too much. The lead was surprisingly kickass, for a guy who only walks around, smoking cigarettes. Villains made sense and did their jobs, mostly. Mauve, Chief, idiot prince, and the supporting cast all the way down to Knot, Warbler, and even Rail -- everyone contributed.
