But deciding "Is it, or isn't it" is not cut and dried. Take one that Nolte didn't list, The Big Lebowski. A good many people think this movie is noir. If my memory serves, some of us here, however, question calling this movie noir.
Not having any important stake in such quandaries, I personally wonder whether or not a film entertains me and has some features I like. The label "neo-noir" tends to help me find such films. The Big Lebowski is such a film, and the label led me to it.
It's going to be a challenge to articulate a collection of attributes that select a film with a neo-noir caste to it and do so without sometimes significant disagreement. Making these attributes easy to apply objectively by anyone will be a challenge. Not impossible, but a challenge.
There are many people who call many films neo-noir and even make lists. There is no known simple or objective way to categorize which of anyone's films are neo-noir. The lists do not agree as much as one might prefer.
Neo-noir is a methodology and its practices vary in strength and application. It's also an amorphous methodology in some respects and a term of application that's dynamic (changing). This helps make it a challenge to label films.
