The dearth of – and appetite for – films featuring older protagonists was demonstrated by the success of The Best Exotic Marigold Hotel and its sequel. So in theory, this light-hearted comedy drama about a group of OAPs who decide to supplement their pension shortfalls with a crime spree should find a receptive audience. In practice, however, despite a likable cast of television and theatre stalwarts, this limps along like a botched hip operation. The production values lack polish and the performances lack vital life signs, but the main problem is a screenplay (co-written by Nick Knowles, present of DIY SOS) that leans heavily on jokes that are older than the cast and that stopped being funny several millennia ago.
