"Black Mirror" is a science fiction series that opens a window and lets us peek into a future that seems to be getting closer and closer. I´m a fan of this show since it started in 2011 and despite its acquisition by Netflix in Season 3, nothing has been lost in terms of creativity and every episode of this Season 4 continues to offer us stories in a future that feels more and more present. By the way, this is the characteristic that I like the most in this show, the future is strangely familiar and plausible, as if what we are seeing can actually happen in an increasingly technological world that still keeps much of what we know today. Each episode presents us with a new story with new themes and characters, always maintaining the background that characterizes the series, a future that may be more or less black and dystopic and in which we are confronted with the consequences of the use of technology in the evolution of the society and the human being. There are always many and complex questions that stand at the end of each episode and insist on staying in our thoughts. Perhaps because of this, "Black Mirror" is a reference to the effect of a TV screen or computer that, when off gives a dark reflection of the viewer. My favorite episode continues to be "Nosedive" of Season 3, which shows a society that lives by the rules of a social network and where the success and happiness of each one is decided by the evaluations given by others (it does remind us of something familiar, does it not? ). This season, the episodes "USS Callister" and "Hang the DJ" are my favorites, the first being a satire to the classic sci-fi shows, full of black humor and that makes us think to what extent virtual clones are conscious beings, and the second a vision of relationships and soul mate search through algorithms of an advanced virtual dating system.Thanks Netflix for having started the year in the best way and I can only hope that this is just the beginning of a 2018 full of such good quality series. GOOD - creativity, innovation, black humor, the ability to surprise, reminiscences of "The Twilight Zone", thinking the future BAD - few episodes VERDICT - excellent, a must see
