From its opening frame featuring a down-and-out Emma Stone (a mesmerising performance) in a half-retro, half-futuristic New York, Fukunaga stuns with sumptuous scenes and wonderful cinematography. Jonah Hill is perfect as the hallucinating depressive son of a scion. In the second half the two volunteer into a pharma’s clearly dodgy group trial, and the signals are clear that this is going to be one trippy experience, perhaps a la Legion (one of my faves from 2017), and that the clashing duo will team up. All the bit players are superb. Not a moment of Maniac is wasted, not a moment is predictable. What a stunner of an opening episode!
