'Stranger Things' season 5 finale is basically four feature films back-to-back

Forget binge-watching—'Stranger Things' Season 5 is asking fans to commit to what's essentially a quadruple-feature movie marathon.

The runtime breakdown for Volume 2 is wild. With three episodes dropping Christmas Day and the finale arriving New Year's Eve (hitting theatres too, naturally), viewers are looking at nearly 7 hours of pure Hawkins chaos spread across those final installments.

This isn't your typical TV finale. Each episode clocks in with movie-length runtimes, turning what could've been a standard season wrap into an epic saga. The Duffer Brothers clearly decided if they're going out, they're going out big.

And they'll need every minute of that screen time. Volume 1 already packed in Demogorgons tearing through Mike and Nancy's house, Vecna kidnapping their sister Holly, Max mysteriously awake from her coma and trapped in the villain's memories, plus Will finally unleashing hidden powers to control monsters during a military base massacre.

The entire original cast returns for this supersized sendoff: Millie Bobby Brown, Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, Winona Ryder, David Harbour, Sadie Sink, Joe Keery, Maya Hawke, Charlie Heaton, Natalia Dyer, and Jamie Campbell Bower, joined by newcomers Nell Fisher, Linda Hamilton, Alex Breaux and Jake Connelly.

The stakes? Vecna survived a full military assault without a scratch and now wants to reshape reality itself. Hawkins remains under lockdown with soldiers hunting Eleven while Demogorgons keep crossing into the real world.

So clear your holiday schedule. This finale requires the same commitment as settling in for the entire 'Lord of the Rings' extended edition—except with more 1980s nostalgia and interdimensional monsters.
