The craziest thing about “Upgrade,” though, is how closely it mirrors (pun intended) the series Black Mirror. In my previous review, I mentioned Black Mirror as a comparison because of the somewhat dystopian atmosphere created by the technology, but “Upgrade” reminded me so much of the episode “The Entire History of You” from Black Mirror. If you haven’t seen that episode, I highly encourage you to check it out on Netflix. Whereas Black Mirror shows you what could possibly happen with our extensive use of technology, Dark Net shows you what is already happening because of it. If nothing else, Dark Net is a fantastic companion series to the other.
