This show has everything...! Great characters, story, 60s set pieces, the acting and directing is quality. You gotta love a well made period piece that is well paced, even though each episode is long, and you can't wait to see what unfolds in the next episode. It's based off a 1980s book of the same name, and both actresses that play the lead really nail their work. The actress that plays the young Beth early in the series set in the orphanage, is such a talent she sets up the story well as it jumps ahead in time to her teenage years. It was a very original and interesting story line, and importantly, engaging... The process the main character uses to learn and develop her Chess game was entertaining from the outset, and continues to be explored as the story develops beyond the orphanage. Well worth a view.
