Inception Review

Nolan's premise could have collapsed into gibberish, and the reason it does not is discipline: the dream layers obey stated rules about time dilation, kicks, and the projections that turn hostile, and the film never breaks one for convenience. That rigor lets the third act run four timelines at once, van and hotel and snow fortress and limbo, without the audience losing its footing, which is a feat of construction more than of spectacle. Wally Pfister shoots the Paris street folding over itself and the rotating hotel corridor as physical events, because they were; Nolan built a spinning set and let Joseph Gordon-Levitt fight inside it.

Leonardo DiCaprio plays Cobb as a man managing his own guilt like a security risk, and Marion Cotillard's Mal is the one element the rules cannot contain. The cost is dialogue: characters spend long stretches explaining the machinery to Ariadne, and the exposition is audible as exposition. But the ambition earns the load, and that final unresolved wobble remains the decade's best last shot.
