Quick impressions: The big minus is the character of Mira, the governor's daughter, who is more irritating than anything else. To be honest, the character feels tacked on to the story, and the rest of the story likely works without her just fine. On the plus side, I liked seeing Cain's relationship with the Space Marines, especially with the techmarine. Overall this was good, but not great.
