Denis Villeneuve’s Dune is beautiful to behold, a faithful adaptation of Frank Herbert’s novel. Or of its first half, that is. And therein lies the problem that the film faces, for in cutting this story into two parts, Villeneuve has front-loaded Dune with a lot of set-up and no obvious way to end things… and so it lingers, and eventually overstays its welcome. This is a technically brilliant, visually amazing movie with a top-notch cast and deep sci-fi concepts. A shame, then, that it feels like a drag in its back half.
