I mean, there's this whole thing where you can sort of trace the 'Nordic Noir' DNA back to (I think) Forbrydelsen, which was the original/Danish version of The Killing. Then the US Killing, then Broadchurch (and the failed US Broadchurch) then a million tertiary shows like Marcella. "Troubled female detective battles crime and her own demons while grappling with motherhood, usually in a small town but not always."
While it's part of that club, Happy Valley does have its own very specific thing, a lot of which mirrors the setting of MoE. But ... that's just based on the one episode for me
