Not exactly an inaccurate literary reference as such, but it really does disappoint and frustrate me when (inevitably) beautifully crafted period dialogue (particularly if witty, as in the case of Austen) is firstly slashed to shreds by TV screenwriters in order to pare it down to the bare coat-hanger plot minimum and then crudely wedged back together with a trowel-full of "sore thumb" anachronistic phrasings and idioms, innit?
