Movie-style romance may never look quite the same. Neither will flower petals.

It's difficult to overstate how much of a rare find this movie is. Colombani and her cast remind us that the best thrillers are built upon superb writing and strong acting.

This is an acerbic examination of erotic obsession, told from different perspectives, with wit, suspense and cold-blooded detachment.

This genre-busting movie has the appearance of a love story but morphs into a thriller, told cleverly in a nonlinear style. Think "Sliding Doors" crossed with "The Sixth Sense," with a little "Memento" thrown in.

Turns on an intellectual gimmick in the vein of "Memento," weaving down sinister byways, the better to click with satisfying symmetry.

Wickedly clever.

Mercifully there's more Hitchcock than Lacan in this slickly enjoyable little number, which cannily plays off the ingénue image of "Amélie's" Audrey Tautou.

May not change the world, but it's deeply creepy and richly satisfying.

An impressively assured and confident first film and has been made with such attention to detail and mood that it's possible to regret not paying closer attention to its cleverly deceptive first part. It is ultimately unsettling in the utmost, its creepiness leavened by only the slightest touch of pitch-dark humor.

Colombani has created uncommonly arresting entertainment.

Poses a problem for reviewers. The entire story hinges on a plot device that occurs roughly midway through the film and alters everything that has come before. To give away this massive, unavoidable spoiler would be disastrous and unforgivable.

Perhaps not since Truffaut's "The Story of Adele H" has thwarted love been rendered so compassionately on the screen, its psychology laid bare.

The film holds charms for everyone but in a very unusual way: If some audience members feel cheated at the halfway mark, others will feel that the film is finally getting started. Nifty!

The fact that it's difficult to believe someone who looks as dewy as Tautou would be so dangerous is much of the game.
