It's hard to avoid calling Flawless a heist movie, but anyone who puts too much stock in that description is bound to come away disappointed. The movie has a couple of things going for it, but the big jewel theft at the center of the story is a wash-out, only marginally more convincing than the criminal idiocy Diane Keaton and Queen Latifah perpetrated a few months ago in the instantly forgettable Mad Money.

Demi Moore stars here as Laura Quinn, an ambitious female executive repeatedly passed over for promotion at the London Diamond Corporation, while a series of less-qualified males sail right past her. With her head bruised from banging against that glass ceiling, Laura finds herself listening closely when an aging night janitor (heist-movie icon Michael Caine) approaches her with a plan to rob the corporation blind.

The planning and execution of the heist turn out to be fairly perfunctory and rather uneventful, with director Michael Radford (Il Postino) spending more time dwelling on the post-crime investigation and ramifications — neither of which proves terribly interesting. The film is pleasant enough to look at, however, with solid production values and meticulous attention paid to its 1960 time period — but most of the performances (beginning with Moore's) are modulated to the point of lifelessness, and the movie is way too methodical for its own good. It's all bookended by some laughable latex make-up on Demi at the outset, and some annoyingly simplistic moralizing at the end that leaves an unpleasant taste in the mouth.
