Because God loves us, we get to watch never-before-seen Stranger Things footage. And it's not scary, but funny, because it's bloopers from the set. Of course they had retakes. And they are the best.
This first blooper reel is from season three and dropped on the 6th (Stranger Things Day). That's the most recent season that took place at Starcourt Mall. Between now and Christmas, they'll release bloopers from season one and two.
