“Stranger Things” drops on Netflix (July 4). It’s the summer of 1985 in Hawkins, Indiana and Eleven (Millie Bobby Brown) and her friends are navigating pre-adulthood, a romance among the group, and a new mall. The only problem is the ever-present evil of the Upside Down that threatens to destroy them. The action-packed series is a clever compilation of ‘80s movie genres with a likable cast.
