It also helps us to track and rationally set aside the films that don't belong in a "neo-noir" setting due to the increased "genre diffusion" that has ensued in the world of filmmaking over the past 25 years.
There are also ways to break down the longer lists to make them more manageable without resorting to auteurism, which also gets in the way of analyzing neo-noir, which creeps into films in various ways and should not be subordinated to cults of personality.
But, to deal with the ones you've already brought up, here's my take. The ones with arrows <--- represent my critical judgment; the ones with arrows ---> are ones that require consideration because of their reputations, which I don't personally agree with.
Which of Scorsese's impressive list of neo-noirs might make a top 25 list? Or a 26-50 list? Sort into the 2 tiers.
Mean Streets (1973)
Taxi Driver (1976) <---
Raging Bull (1980) <---
After Hours (1985)
The Color of Money (1986)
Goodfellas (1990) <---
Cape Fear (1991)
Casino (1995) <---
BRINGING OUT THE DEAD (1999)<---
Gangs of New York (2002)
The Departed (2006) --->
Shutter Island (2010)
Same questions for Brian De Palma:
Sisters (1972) <---
Dressed to Kill (1980)
Blow Out (1981) <---
Body Double (1984)
Carlito's Way (1993)
Femme Fatale (2002) --->
The Black Dahlia (2006)
I do not think that David Fincher is in the same class as the above two, so the question doesn't come up.
For David Cronenberg, I think there is a small number to consider:
Crash (1996) <---
A History of Violence (2005) <---
Eastern Promises (2007) --->
For Steven Soderbergh, entries to sort are
The Underneath (1995)
The Limey (1999) --->
Traffic (2000) <---
Side Effects (2013)
Out of Sight (1998) and The Good German (2006) are ones I'd dismiss without recourse.
Writer Hossein Amini has two very good candidates:
The Two Faces of January (2014) <--- "neo-retro-neo"?
Drive (2011) --->
I'd say this group (<---, --->) represents possibles for a Top 50-75 list, with some being high on the list, and others not. Anything arrowless is not in the running for Top 200 (IMO).
The subsequent task is to look at all the other films not covered by Silver and the "auteurist" list here and factor them into a candidate pool that's somewhere around 150 or so in number...
