It's 2384 and having been put ‘on ice' for 250 years, Takeshi Kovacs has been brought back and leased to Laurens Bancroft to help him solve a murder. Netflix's Altered Carbon is set in a time so advanced that every person has a cortical stack implanted into their spine which is like a storage device for memories and the physical bodies that humans inhabit are interchangeable and synthetic “sleeves” which are used as vessels that can accept any stack. In this case, Kovacs awakes in a sleeve formerly belonging to another person which has been upgraded to enhance his mercenary skills.
Kovacs is the sole survivor of those defeated in an uprising against the new world order 250 years prior. He was an Envoy, part of the resistance, against the Mets who now rule the world and to whom he is beholden. Caught between his hatred for Mets and his desire to live, Kovacs must solve Bancroft's murder or risk being put back on ice for the rest of eternity. Along the way he garners a couple of associates who for their own reasons help him out in a quid pro quo sort of way. Ortega is a police detective who has been tracking him for reasons we discover later into the series, Poe is an AI (Artifical Intelligence) who runs the hotel and Vernon needs Kovacs to help him save his daughter.
There are also plenty of sub-plots and the futuristic dystopian view of the world is brutal at times, as are the fight scenes. It is a dark, gritty and frequently grim look at life in a world far into the future but it is also gripping and addictive and a show that you absolutely have to pay attention to if you want any chance of figuring out what it going on. It is jam-packed with action, guns, crime, an injection of much needed humour from Poe, amazing special effects and some kick-ass fight scenes and has score of 8.2/10 from over 79K votes on IMDB. Is it action? Is it Sci-Fi? Is it crime? Is it drama? Actually it's all of them and that's what makes it so good. And if you can't get enough of it, it also has it's own Twitter page for you to follow.
