And that’s precisely how I want my sci-fi. If it looks good, then that’s a nice bonus, but ideally a good show is not only entertaining and visually pleasing, but also challenging with a mesmerizing story. Some of the best shows even make us slightly uncomfortable in the way they raise difficult questions, often around ethics and morality. At its best, sci-fi really makes us think about what kind of a future we want to build for ourselves.
