A few oddities or inconsistencies (like placing food as a requirement for survival above water), or this same scientist thinking that every "neuron" in her body hurts. Granted, her PhD is in Film, but they keep referring to her as a scientist - in itself, another oddity. Though I guess maybe she is technically a Social Scientist? She apparently has a research PhD, so at least there's that.Other than the niggling inconsistencies, emotionally it was gripping and rang mostly true. I thought Casey was waaaay too dismissive of being told her brakes were cut, but I guess I could see that as being in character for someone who wants to see only the good.Overall I really enjoyed it, but definitely had some niggles. Like the villains being so totally villanous. I think they could so easily have been multi-faceted, sympathetic characters in their own right even while working at cross-purposes to the protagonists. I could already see reasons why they might be/act as they did, so with just a little more effort the author could have reallyl brought them to three-dimensional life. As it was, they were annoyingly simplistic and evil. Bleh.
