Along the way it provides the grand, intelligent entertainment of a superior cast playing smart people amid a compelling plot. It may not be perfect, but it's decidedly a cut above.

A riveting and surprisingly romantic ride.

It is such a grand, romantic entertainment that it sweeps the viewer along in its swiftly escalating suspense.

With a cast of actors playing some of England's smartest people and with a crackling script by Stoppard -- no slouch in the brains department -- it pays to stay awake.

Uses the compelling true story of the triumph of the Enigma code-breakers as background for an invented but believable story of love, betrayal and heroism.

It's brainy and brilliant, but despite amorous overtones and a few good action set pieces, it just doesn't generate the thrills or romance that would have made it a true classic.

Period re-creations so rich you can taste them, and the fine cast.

Intelligent, involving and intricately plotted thriller.

Enigma is not for everyone, but the thoughtful (and the historically minded) will find it an absorbing and extremely well-textured experience.

It's done with such a wonderfully dry style and wit that you don't mind having to stop to catch up now and again.

A smart, old-fashioned spy thriller in which the weapon of choice is brainpower.

With its combination of intrigue, romance, and adventure set against a World War II backdrop, the movie has an undeniable appeal. Flaws aside, Enigma is engaging and ambitious.

The combined talents of Apted, Stoppard and the stellar cast make Enigma a puzzle worth solving.

The film manages to crack all its codes, and even when it sags a bit, it's never lacking grace and some wit. Not enigmatically at all, it pleases and teases us -- in high style.
