Black Mirror is the most hard-hitting hypothetical on the psychological horror of unhampered technological advance I've ever seen... it reminds us that the potential side effects or opportunities for abuse are as limitless as human nature, and easily as devastating as biological tampering. Our current reckless obsession with pushing forward and rolling out new gadgets and systems without ANY thought for the potential consequences, combined with our smug self-assurance that technology is always beneficial to humanity is truly what makes this terrifying stuff. Guns in the hands of children. A brilliantly conceived and written show. I could not fault the acting, editing, camera-work, set pieces, soundtrack, scripting or effects. I honestly haven't been blown away by such a genius social commentary since... well forever. Do yourself a favour and watch them all. You may find yourself looking at your mobile phone with a strange sense of revulsion afterwards. Not to mention the internet.
