I'm writing a couple of screenplays based on some noir-ish PI novels I've written. Two of the three are written in 1st person and lend themselves to VO in the screenplay. I agree that VO can be overused, improperly used and is generally frowned upon, but if the genre lends itself to VO, is it more generally accepted in the industry?
The best example of its use was Kiss Kiss Bang Bang (at least in my opinion). Not looking at THAT much, but in a similar vein.
