What a way to round of a superb series of Black Mirror. I'll admit my anticipation levels were high for this one, and I was not left disappointed. Instantly this was absorbing, it unfolded in real style, loaded with twists and turns, captivating viewing from start to finish. Technology used in true Black Mirror style, used to make a wonderfully twisted, but human story. Fabulous acting from all, Letitia Wright was fabulous throughout, particularly at the end. I've always been a big fan of Douglas Hodge, he seems to have been off the radar somewhat, so it was great to see him back, he was excellent, impressed by his accent too . At times it felt like a seventies portmantaeu film, lots of stories within a story, all combining at the end, similar in layout to 'From beyond the Grave.' This one seemed bigger and bolder, had the feeling of a quality film about it. Very impressed.
