No, no shame on you. It's your opinion, and it's not wrong, per se. I consider Glasslands a waste because a major plotline was not used to deepen the character or provide world context or to even provide a message for the reader. Traviss took the most developed character in the fiction and used her and the surrounding characters as a vessel to preach her own views. And she also had the nerve to summon up contrived characters and circumstances to validate the character assassination that took place.
We all know Halsey did some shiesty shit, and that her most recent actions were to atone for those crimes. But instead of providing more information on her (and the S2 program's) past in order to shed some light on her demons, Traviss tackles the issue with clumsy hyperbole (comparing Halsey to 20th century dictators) and completely ignores the moral crisis Nylund wrote her into.
As a result, the most busy and plot driving character -- aside from the AI modeled off her brain -- did fuck all for an entire book. She just took shallow hits the entire time that provided NO NEW INFORMATION for the reader to digest.
