There's nothing subtle about this unrelentingly grim adaptation of a literary sci-fi novel that's been selling like bootleg sex tapes in recent political years. (In the month after Kellyanne Conway's infamous utterance about 'alternative facts,' the book skyrocketed to the top of Amazon's bestseller list.) The catch phrases that chilled your blood when you read the book - 'thought police,' 'newspeak,' 'doublethink,' 'thoughtcrimes,' and, of course, 'Big Brother Is Watching You' - are spoken on stage and projected on screens of a chillingly futuristic set designed by Chloe Lamford.
