A superb question J-man. However, Ancient has answered exactly what I was thinkingm, it would be superflous for me to post my thoughts.
I will say its a shame about the lack of it, because as a Genre it is, possibly, one of the most interesting out there, unfortunatly I dont think the talent that is out there is looking to make a Noir picture. Mores the pity says I.
Hey, careful, man, there's a beverage here!
