The four, hour-long episodes in this mini-series do not make concessions to try and over-explain the world-building and concepts: the assumption that the viewer is already either really familiar with the Witcher-verse or that they would Google and fill in gaps. This achieves two things: the stress of a clever introduction is gone, and the series gets right down to the brilliant fight sequences, poetic Nordic cinematography, excellent sound score, and funny one-liners.
If you are wondering if we see a glimpse of fan-favorite Geralt of Rivia, you may be disappointed. However, the series features the familiar lovable contribution of a bard. A Seanchai tells the story of the first Witcher to Joey Batey's Jaskier, who vows that he will sing the tale.
