After nine years, 41 episodes, and plenty of nail-biting moments, the last episode of Stranger Things finally debuts on December 31 in theaters and on Netflix, bringing a close to one of the most-talked about sci-fi dramas in recent years.

Finally, after what feels like a hundred years, “Stranger Things” has ended.

As the dust settled on the Upside Down for the final time, the Stranger Things Season 5 finale titled The Rightside Up concluded on a rare note for a global phenomenon.

Season 5 of Stranger Things wrapped up nearly a decade's worth of storytelling with the emotional finale The Rightside Up, with fans (reluctantly) saying goodbye to Hawkins’ beloved inhabitants in the feature-length episode.

The second part of Stranger Things Season 5 has finally arrived on Netflix, building anticipation for the series finale, scheduled to release on New Year's Eve.

The Wednesday, December 31, series finale saw Eleven ( Millie Bobby Brown) and the Hawkins gang finally defeat the villainous Henry Creel/Vecna ( Jamie Campbell Bower ), but not before the show offered key insights into the antagonist’s backstory.
