Caroline Framke Chief TV CriticImmediately upon opening “Stranger Things” Season 4, Volume I, you might notice that the shortest episode runs 62 minutes, the longest a solid 98(!), and the average around 72. Your reaction to this (not to mention the fact that the final Volume II chapter premiering in July will feature an astonishing run time of two and a half hours) will likely dictate how much you’ll enjoy this fourth season in general.
