season 4 is here. And it promises to deliver a satisfying -- if not deadly -- end to the biggest, most watched installment of the Netflix original series from the Duffer Brothers. With Vecna showing no signs of slowing down, Eleven (Millie Bobby Brown) struggling to regain her powers and the gang split between Hawkins, Indiana and California, things are not looking good as our favorite high school heroes prepare for the battle of their lives. And based on comments from the cast, notably Joseph Quinn, who joined this season with the breakout role as Eddie Munson, not everyone will make it out alive.
