The people around me reacted with the eewrrgh sound that has become de rigueur in the viewing of violence, followed by the traditional hasty giggle to pop the tension; even those moviegoers who revel in such a sight, however, might usefully pause to inspect the kick of pleasure that it provokes. No doubt they will have seen much worse, and they will also know that a bursting brain is no more real than a game of Quidditch, yet what perturbs me about a film as careful and as intelligent as “Drive” is its manifest delusion that, in refusing to look away from the minutiae of nastiness, it is actually drawing us closer to the truth about pain.
