Though often dismissed as chick flicks with manners, middlebrow literary costume dramas of the Merchant Ivory school brought a slate of virtues to the cinematic landscape. At a time when action flicks were taking over, they celebrated the pleasures of rounded storytelling, and even their proverbial theme — the tug-of-war between love and money — was tougher than it looked: At their best (A Room With a View, Persuasion), these films anatomized romance, that dance of the spiritual and the worldly, as few other movies have. Nevertheless, the genre, in recent years, has faded, a casualty of shifting tastes, and that makes it reasonable to ask: What could the dozenth adaptation of Jane Austen's Pride & Prejudice, with lush photography and Keira Knightley, bring to the party?
