If it happens to be date night and you and your fancy fancy seeing a run of the mill cinematic chestnut of romance and will they/won’t they, with two leads garnering Golden Globe nominations for their performances, then waste your money on Love and Other Drugs. And make the most of sitting in the back row. Blue Valentine is not for you. It may be gentle and humble, but also honest and pathetic, and lives squarely up to its downcast title.
