This is good old-fashioned pulp science fiction. Do not expect a lot of scientific verisimilitude. For that matter, do not expect a whole lot of verisimilitude of any kind. Do expect interstellar adventure and intrigue. Do expect villains of the purest evil. Do expect galactic emperors and other space faring nobility. Do expect a dashing hero who must be perpetually rescuing the gorgious star princess. Do expect a lot of escapist excitement, but not a lot of depth.
