A gorgeous, fantastically sinister moral fable about the cruel predictability of human nature and the way entire systems — from carnies and con men to shrinks and Sunday preachers — are engineered to exploit it.

Stunningly-detailed, with an A-list cast up and down the line, it’s a gorgeous and gloomy dip into the dark side, immersive and bleak from start to finish.

With a semi-playful nod to the 1945 film Detour and more than a few rain-drenched streets, Nightmare Alley pays tribute to noir. But it’s also its own dark snow globe, luminous and finely faceted, and one of del Toro’s most fluent features.

A wickedly enjoyable tale of freak shows, dark and stormy nights, innocent dames, morally bankrupt schemers, and a femme fatale to die for.

This sordid excavation into the hollowness of a human soul is a strange fit for a director who’s spent his career searching for magic in the darkest margins of our world, but del Toro’s natural empathy for even the most damnable creatures he finds there sparks new life into “Nightmare Alley” as it narrows towards its inevitable dead end.
