Altered Carbon has arrived on Netflix, introducing an expansive new sci-fi world where bodies are disposable and immortality is achievable. Joel Kinnaman plays Takeshi Kovacs, a rebel fighter who was imprisoned for his role in an uprising against the Protectorate, and whose stack is transferred into a new sleeve by a Meth who came close to real death, and who wants Takeshi to find his would-be killer.
Confused by that terminology? You're probably not the only one. Altered Carbon has plenty of sci-fi terms specific to its futuristic world, delivered in quick succession and used frequently throughout the show.
