I feel the same. Season 1 of Altered Carbon was awesome and the second season was still pretty good, so it is disappointing to hear that it got canceled.

My favorite aspect of the show is the sleeve technology. I love how they use it to explore the idea of immortality, particularly what happens when immortality becomes a commodity that anyone can extend their life as much as they want. On one hand, you have rich people who can buy the best 'sleeves' using to become planetary overlords and in some cases, almost like gods. While, on the other hand, you see the poor who can't afford cloned sleeves decide to die after a few lifetimes. The fact that they managed to tell this story within a murder mystery in Season 1 and a (maybe?) political thriller in Season 2 was very entertaining.

It's too bad they didn't get enough viewers to justify a third season. There's so much world-building left. I'm inclined to read the books now. My best hope right now is that they give the producers of the show a chance to make a final movie. Just something to wrap things up for fans like they did with Sense8.
