“Movies end, even obliquely, while television shows are specifically designed to go on and on, giving movies a satisfying narrative compactness and resolution that television can rarely match. The emotional gut-punch of a film such as the recent British thriller Kill List gains its power in part because when it’s over, that’s it, audiences are left reeling to grasp for themselves the death blow of the film’s moral sinkhole and sort through their own feelings without the cushion of more to come.”
