13 Reasons Why

Timeslip is a British children's science fiction television series made by ATV for the ITV network and broadcast between 1970 and 1971. The series centres around two children, Simon Randall and Liz Skinner who discover the existence of a strange anomaly, known as the “Time Barrier”, that enables them to travel in time to different historical periods in alternate pasts and futures. The two children have contrasting personalities; whereas Simon is studious, Liz is something of a tomboy, and this often leads to conflict between the two. However, as the series progresses, their antagonism matures into a deep bond of friendship. The main theme of the series is concerned with the way mankind uses – and abuses – science and technology. It explores how the pursuit of scientific knowledge and advancement can lead to the depersonalisation of individuals and the abandonment of moral principles. A secondary theme – explored in the instances where Liz and Simon encounter potential future versions of themselves – concerns the extent to which an individual can change according to the situations encountered in his or her life.
