Season 4 volume 1 is fantastic. I love how the duffer brothers have slowly increased the horror and gore as the characters got older which enabled a more sinister take on the upside down world.

These kids are now in high school so the natural progression of the show would to make it around a 15 certificate which then allows it to move along with how the cast have grown up. Great work.

You can tell the duffer brothers were heavily influenced on classic 80s horrors when they were young, from the score, the settings and the main protagonist!
