Stranger Things is one of Netflix's biggest hits. Fans were so hyped for the last two episodes of Season 4 that Netflix crashed as soon as they went online.
One thing that stood out about Stranger Things Season 4 is the length. Even though Season 4 only had 9 total episodes, the runtime for each one was a different story. In total, Season 4 of Stranger Things ran for well over 13 hours, with the season finale clocking in at nearly 2 hours and 30 minutes.
Granted, every minute you spend watching a Stranger Things episode is time well spent, but it appears that even the showrunners thought that the length was excessive.

In an exclusive interview with Collider's Steve Weintraub, the Duffer brothers revealed that they want to keep Season 5 closer to the ten-hour mark.
