Comedy goddesses on the small screen, whether individually in 30 Rock and Parks and Recreation or as a lethally snarky double act hosting the Golden Globes, Tina Fey and Amy Poehler are not quite so divine on the big screen in the fitfully funny Sisters.

Not that there’s anything wrong with their chemistry. Playing wildly mismatched siblings sent into a tailspin on learning that their ageing parents (Dianne Wiest and James Brolin) are selling their childhood home, the pair strike their customary sparks off each other.

But when Fey’s flaky single mom and Poehler’s earnest do-gooder decide to revisit their teenage years and hold one last wild bash in their old home – reversing their former roles on this occasion so that habitual ‘designated mom’ Poehler can finally let her freak flag fly – the barrage of raucous gags the film unleashes contains as many misses as hits.

Sisters is further proof that Hollywood has finally become an equal-opportunity employer where the gross-out comedy genre is concerned, but as the f-bombs rain down it’s hard not to feel Fey and Poehler deserve a far sharper and smarter vehicle for their talents than this.
