The fifth and final season of "Stranger Things" concluded, addressing numerous character storylines and supernatural elements, while leaving several plot points unresolved. Certain character arcs received definitive conclusions within the finale. Mike Wheeler (Finn Wolfhard) was depicted pursuing a career as a writer, and Lucas Sinclair (Caleb McLaughlin) and Max Mayfield (Sadie Sink) were shown together. Jonathan Byers (Charlie Heaton) pursued filmmaking, and Joyce Byers (Winona Ryder) and Jim Hopper (David Harbour) became engaged.
The supernatural narrative of the series concluded with the vaporization of the Upside Down dimension. Furthermore, the alternate dimension known as the Abyss ceased all contact with Earth.
However, the finale did not provide definitive resolutions for several plot threads. These include:
- Specific aspects of the military storyline.
- Certain details concerning the Abyss dimension.
- The ultimate fate of the character Eleven (Millie Bobby Brown). The series creators, the Duffer Brothers, indicated this particular outcome was intentionally left ambiguous. The unresolved nature of Eleven's future has subsequently led to various fan theories.
