If there is no other take-away from this one it is that time-travel is messy. The ethical qualms faced by some of the older characters as they wrestle with the unlived-lives of parallel selves in parallel times was perhaps the most interesting human aspect of the story. What types of cognitive equipment could we possibly have to assess our own actions in regards to the existence of a self we can never know?
Part of the issue with the script format is the asymmetry in which we are presented the characters. The original cast has been fleshed-out for us through stories providing insights into their actions and personalities. The new characters here only present us with dialogue through which to piece them together. As a result Albus Severus and Scorpius are shadows compared to more familiar characters. Much of this may be obviated on stage; in book form it serves to move the emphasis away from the primary protagonists. In the end it feels like a bit of a rushed job. Nevertheless the wizarding world remains a rich place and enjoyable to revisit.
