If you're a fellow fan of the high-tech Twilight Zone that is the BBC's Black Mirror and last year's Christmas special with Jon Hamm didn't sate your craving for more, you won't want to miss the sci-fi creep-out Ex Machina. (If you're not a fan of Black Mirror, which is currently streaming on Netflix, you clearly haven't watched it yet. Get cracking.) Like a 105-minute episode of that haunting anthology series, Alex Garland's quasi-futuristic morality fable boasts a simple premise that grows more complicated and nightmarish as it progresses. Also like a super-sized Black Mirror, the experience leaves you feeling a little shaken and happily freaked out, and kind of antsy to see it again.
