Netflix’s new teaser for "Stranger Things" season 5 gives fans a glimpse of the final battle, with Eleven, the gang, and the Upside Down all returning.

As of July 2025, Netflix hasn't officially revealed the duration of individual episodes in Stranger Things Season 5. That said, several interviews featuring the Duffer Brothers and cast members have provided us with an idea. Most Season 5 episodes are reportedly going to be shorter than the way-too-long Season 4 episodes. The estimate as of now is:

Stranger Things season five volume one streams November 26. Volume two arrives at Christmas, and the series will culminate in an epic finale on New Year’s Eve.

The official teaser trailer for Season 5 previews a final battle with Vecna, whose complex origin story is the focal point of the play "Stranger Things: The First Shadow."

Nobody needs to be Rickrolled after three years between seasons.

Stranger Things fans reckon they've worked out which two characters will die in the Netflix show's fifth and final season after spotting a 'spoiler' in the new poster
