This show succeeds in everything FX's Legion tried but hasn't quite managed to pull off, diving into mental illness and investigating what the mind looks like when it's not working well, and what it means for a mind to function well in the first place. Emma Stone and Jonah Hill are both stellar in the lead roles, but it's Cary Fukunaga's mesmerising direction of all 10 episodes that lifts this show into masterpiece territory. Every frame and shot is meticulously crafted and visually stunning, and both these and Fukunaga's superb use of Dan Romer's quirky score help create the disorienting and nervous but still somehow light-hearted atmosphere that draws you so deeply into this strange, retrofuturistic world(s) and the wonderful minds of the characters who inhabit it.
