One of the best ones of the series if you ask me, and a true insight into the role of human grief.

It's also is an eerily accurate prediction of things now (about 10 years after release) very much possible.

Also see the film Majorie Prime

There's also a great Adult Swim Infomercial satirizing this idea, "Live Forever As you Are Now with Alan Resnick"[1]. Apparently it came out the same year as that Black Mirror episode (2013) !

I think Inside No. 9 also had an episode on this theme. It’s a seriously underrated show and practically unknown. It sort of occupies a middle ground between Black Mirror’s dark satire and Resnick’s absurdist realism, now that I think of it.
