"The Hellfire Club" starts season 4 of Stranger Things off with a bang (or should we say, crack)?  With a significantly darker and more horror tone than previous seasons, the group of Hawkins kids are more splintered and dysfunctional than ever before.  Max is facing significant challenges with her family and personal feelings after the death of Billy and breakup of her parent's marriage, El, Will, and Jonathan are trying to adjust to a new town in California, while Lucas, Mike, and Dustin adjust to life in high school which has them pursuing interests that are testing the limits of their friendship. We also meet new characters, Jason, Chrissy, and Eddie, which even after one episode, have each given us reasons to form strong opinions about them.
