Stranger Things Season 3 is a brave, messy, and entertaining evolution. It rejects the “repeat S1 formula” trap and instead grows up with its characters—complete with awkwardness, loss, and summer nostalgia tinged with horror. While it sacrifices some mystery for spectacle and humor, it delivers the most emotionally devastating finale of the series. For viewers who accept the mall as a character and the Soviets as cartoon villains, this is peak summer blockbuster streaming.
