Criticism is the systematic reading (that is, evaluation) of texts. Like all other activities, it takes place in the present. Like all other critical activities, it presupposes a principled attitude to the politics which constitute the present. The business of the film critic is to arrive at an understanding, on the basis of that attitude – which ought to be as alert and as conscious as possible – of what is of value in the past and present of the cinema, and to ensure that this value is recognized for what it is, and has the influence it ought to have, now.
