Story was satisfactory, characterization was good for the genre but the military operations seemed amateurish. Particularly with the Marines. Minor spoiler alert! The good guy Marines were boarding a hostile space freighter and the Marine officer in command of 200 Marines was first through the hole blasted in the freighter’s hull! And no one had or threw any grenades into the compartment first. I’ve no military experience but I’ve read enough accounts of real world militaries fighting house-to-house to know that’s not the way it’s done. YMMV.
