There's something satisfying in going from the straightforward simple-minded nihilistic/narcissistic fixation on the "black box" protagonist in the first part to the second part (or, as it is called, the "revenge arc") and its more skillful inclusion of other characters' perspectives (even one that merely lasts two pages before he dies). Historically I think this might be an important novel in the genealogy of a super strong and smart character that outwits and overpowers everyone else, and though it was sometimes dry, it wasn't obnoxiously indulgent and was overall quite a fun read. Some scenes did reach a level of absurdity where it almost felt comedic, from the perspective of a 2025 reader, but there's quite a careful toeing of the line between unironic seriousness and flat out parody. Just imagine a yakuza film in novel form, with pretty detailed descriptions of a variety of guns as well as, in the second part, some pretty interesting and complicated know-how on hijacking a company through cunning financial means.
