Machine Man is a worthwhile read, but there are two things that bug me.

First - character names with the same first letter: Cassandra Cautery. Angelical Austin. Ouch.

Second - Cassandra comes across as a BWAH-HA-HA type of all-evil villain from the evil corporation. I spend so much time disliking her, as a reader I really don't welcome her presence. Other than being a vehicle for info-dumps about the evil the corporation and what they are going to do to Charlie, she's just kind of a flatline annoyance.
