For every old noir movie there are 10 awful ones. And for every good new one there are a 100 stinkers. You’re much better off watching old ones...superior quality in every way. I suggest 1939 to 1959.
Remember, many of the “stinkers” were filmed in less than two weeks, often with budgets of far less than $100,000. They were essentially the equivalent of a single episode of a modern TV series.
One of the somewhat lesser known ones, THE SEVENTH VICTIM, is one you should see, if you haven't seen it before.
