No mention of Dark City in this thread.
2049 also deserves some recognition as a neo noir film.
I consider The Proposition (2005) a western noir and one of my personal favorites.
I watched Dark City a few times and considered it. It has a happy ending, which flat eliminates it from the list. Also a long extended sci-fi sequence that isn't noir. (I assume you aren't referring to the Charlton Heston noir Dark City (1950) with Lizbeth Scott, Jack Webb, Harry Morgan and Ed Begley Sr.)
As for the Batman ilk, Batman is the opposite of a noir protagonist. They are not super empowered billionaires, in this genre. Just a note there. One of the fundamental realizations I had watching all this old genre is it is very specifically about the grimy world of real people doing damage to each other and being unable to beat the system. Batman and superheroes are always fighting other specific superheroes. That says: it's bad individual actors who mess everything up, not simply the weight of millions of apex predators adjacent to each other. We are in pure oppositeville from noir. The complete opposite of that is superheroes with magical powers. It is the complete and total opposite, thematically.
But what happens is, noir is cool. Superheroes are for audiences still a bit insecure in who they are, and they want to be cool, but can only adopt cool at this age, so they adopt the clothing of cool, but they don't understand the authenticity that is in real noir. They'd rather skip over it, it's inconvenient to the burst of significance one gets when they just saw a film and it lit them up inside and they want to say it's the best. The superhero noir fans are definitely the least developed in noir, they don't understand noir, full stop.
