Bitchy histrionics curdle faster than a milky coffee left in the sun in this distinctly unlikeable comedy about a trio of coked-up girl pals who barely muster the strength to celebrate a happier friend’s wedding. Playing parts better suited to the edgelands of ‘Mean Girls’, a trio of dynamic actors do what they can with playwright-director Leslye Headland’s thin, unvaried material: Regan (Kirsten Dunst) is the seething maid of honour; Katie (Isla Fisher) is a sex fiend; and Gena (Lizzy Caplan), most alive when her phone is chucked out of a window, is the caustic slacker, still bruised by a school-days rejection.
The first half hour has the scheming zing of a better episode of ‘Gossip Girl’ (a disastrous prank involving the bride’s dress is shockingly callous). Then you realise that Headland has little interest in exploring the obvious desperation at the root of their toxicity. Still, nice guys flock to our heroines, simply because they’re the main characters. Worse, the movie wants to wrap itself in a belated sincerity that celebrates sisterhood and forgiveness – this when no one really merits it. Not to sound too much like a bratty teen – but, um, why should I care again?
