Luc Besson's new film rehashes 2011's Limitless with guns, cleavage and Malickesque pretensions, casting Scarlett Johansson as a moll-turned-mule transformed by her wonderdrug cargo into a high-functioning badass capable of taking down every last gangster in Asia.

Struggling to metabolise concept into playable character, this Johansson makes an oddly dull and glassy-eyed subject, as well you might be after regular doses of Morgan Freeman exposition; "exciting" shots of nature are therefore spliced in, so artlessly as to suggest projection error. Its sputtering eccentricity is at least preferable to the monotonous chauvinism of Besson's recent writer-producer credits: it's his most enjoyable bad movie in ages.
