With only two seasons left for one of its most popular shows, Netflix is rightfully spending mightily on the fourth season of Stranger Things.

Now, the streaming giant just revealed where the bulk of the budget went.

According to an official blog post, the seventh episode of Season 4 of Stranger Things will come in at one hour and 38 minutes, and we're just getting started. The final two episodes will come in at one hour and 25 minutes and almost two and a half hours, respectively. To put that into context, the longest episode of Stranger Things is the Season 3 finale at 77 minutes. Furthermore, at around 150 minutes, the Season 4 finale will be as long as last year's Spider-Man: No Way Home movie.

All told, Stranger Thing's fourth season will run well over 13 hours, a terribly long affair but a risk that might be well worth it.
