It takes three episodes to really click – an issue when the entire season has just nine episodes (the first instalment releases May 27, the second on July 1). The 1980s-set hit returns with a discombobulated set-up and dispersed ensemble cast. The initial episodes of the blockbuster show’s fourth season require you to consider a new concept: “The Inside Out”. In the paranormal period adventure that is Stranger Things, danger lurks in “The Upside Down”, the nightmarish parallel dimension that co-exists alongside the small town of Hawkins, Indiana.
