Oh man this trailer looks like they are ramping things up in season 4 & going darker. Which is a good thing as they have announced that season 5 will be the last season. I really hope they hit this one out of the park & bring the series to a satisfying conclusion next year. Volume 1 of season 4 streams May 27 . Volume 2 July 1 . That’s going to be a rough month break. But I’m looking forward to visiting the upside down again.
