Netflix has dropped the first eight minutes of the fourth season of Stranger Things, and it’s taking us back to where it all began… a creepy lab in Hawkins, Indiana, run by Matthew Modine.
In a clear homage to Barb And Star Go To Vista Del Mar, the first episode opens with a paper boy on his bike route before reintroducing Dr. Brenner (Modine), who cheerfully returns to Hawkins National Laboratories for a day of dubiously ethical human experimentation.
