Sci-Fi can be... dark. Gritty. A dramatic sequence of hard choices and unforeseen events.
This is none of that.
Reminiscent of Firefly and Star Trek, it is filled with top-notch characterization, questions of morality, and fascinating clashing of culture dynamics. I fell in love with all the characters, both human and alien, and was glad for a reprieve from the heavy stories normal for this genre.
