A bit of an uneven ride, "Un profil pour deux" works mainly as a comedy. That's because the story feels extremely contrived - you don't mind that for a comedy, but anything more serious falls flat if you can't believe in the story or the characters. As to those characters, they're played mostly for laughs, too, except the three leads who have to carry the romance and drama. While Pierre Richard and Fanny Valette are excellent, Yaniss Lespert seems miscast, he's the weakest part of the trio.
While those shortcomings keep it from being an A movie for me, "Un profil pour deux" is still a quick-footed and somewhat cute comedy with some bite to it, too - you won't be bored and you will snicker and smile.
