It's certainly true that there's a LOT of neo-noir out there--some of which gets us back to the "retro/neo" nexus we were discussing with Wisconsin Mark (before he took leave of us again). Its plentiful nature argues for some kind of more systematic survey of what works and what doesn't and why that's the case. I know Gary Deane watches many/most of these and it would be interesting to have him try to survey the scene from such a vantage point--that's not happening in his NC contributions, which seem to be limited to classic-era excavations.
---> In terms of A KIND OF MURDER's genre location, this one looks to be a retro polished up to an almost techno sheen, befitting the other projects that director Andy Goddard is often involved with (lots of neo-cyberpunk variations on TV, for example).
This style of thriller--wrongly accused but somehow still guilty--seems very 50s, but tends to be more lumbering than the variations of the trope that we saw on-screen in the 40s (the murderer unaware of his crime due to repressed memory or post-facto-ex-machina revelation of madness, as seen in BLACK ANGEL and SO DARK THE NIGHT). All of these variants of Poe-like plots really need to conjure up and sustain their dread, which was what was at the root of the Boileau/Narcejac teaming: and it might really take two writers handling this bipartite process to get the tone, rhythm and pacing synced up optimally to keep the reader suspended in mid-air.
