What's the purpose of a BB top 25 anyway? If you ask a dozen people to choose their top 25 films from an agreed upon list of X noirs, where X is a large number like 500 or 1,000, what will the results mean? Or if you ask a few persons to rearrange the old 25 with the option of adding or dropping names, what do the results mean?
All sorts of factors will influence the results, many being subjective weightings and preferences. Popularity, memory (faulty and otherwise), gaps in knowledge, and much more will enter in. What will it all mean?
In the end, the BB vote on the top 25 found some highly-rated films that we could have gotten from Maltin without the vote. His 3 star noirs also provide basically wonderful films.
