I completely missed this show (didn't even hear about it) when it ran for two seasons on AMC, and just binged it on Netflix. It's incredible. Up there with Mr. Robot and other shows, definitely one of the best cartoons I've ever watched. Fantastic acting and writing, and a great understanding of technology.

The plot's complicated, but the basic stuff revolves around a world where the tech to upload human consciousness has just been developed (and isn't without flaws). Takes off from there. It's only sixteen episodes total, and it's well worth the binge.
