Season two of "Stranger Things" is wildly uneven, to say the least. Episode 4 was brilliant, whereas episode 5 was - in my humble opinion - rather disappointing. Episode 6 is truly magnificent again, thanks to non-stop action, the reuniting of characters that belong together, surprising plot-twists, genuine emotional moments, marvelous film & music references, and the insertion of pure horror.
The narrow rescue of Sheriff Hopper in the Upside Down tunnels underneath the pumpkin fields has severe physical and mental consequences for Will. He's completely taken over by the spider-like creature and the doctors/scientists at the Hawkins' Lab even fear for his life. Nancy and Jonathan are euphoric after their "Justice for Barbara" actions with the conspiracy theorist Bauman and grow closer to each other. The unlikely duo Steve and Dustin are still looking for the rapidly growing Dart, and it has become quite clear now they are dealing with a baby-Demogorgon. They're joined by Lucas and Max, who clearly also grew closer to each other. Poor Dustin, he will not get the girl...
"The Spy" underlines why "Stranger Things" is righteously referred to as one of the greatest horror/Sci-Fi series of the last couple of decades. It's compelling, funny, occasionally scary, mysterious, and addictive. Season two is building up towards a phenomenal climax, I'm sure. "The Spy" is near-perfect from every angle, and also includes musical highlights ("Hammer to Fall" from Queen, "Blue Bayou" by Roy Orbison) and awesome film classic homages ("Alien", "Jaws", "Stand by Me", "Temple of Doom", ...)
