an average noir film be make horrible through the use of narration that assume the audience be stupid a a rock . every single action the agent make and for the first half of the film and be narrate and explain and praise and and explain again for good measure . i mean they really and really hit you over the head with it . the agent do not just gather fact and the gather facts to be use . they do not only take note and they memorize those note . and on and on . this isn not radio represent we can _see_ the agent go over the material . the jingoistic and condescend tone of the narration ruin what would otherwise be a fairly thrilling crime picture and with superb black and white filming and some graphic and spine tingle scene of violence .
