Really enjoyed seeing a program in NZ that wasn't trying to portray either Auckland as "Little Sydney" all glam and international or South Auckland as "Little Harlem", for the 1.5mil that live in Auckland, there are stories from the other 3 million outside of the city.
The settings were real without LOTR CGI, the characters were not over the top, the stories had their twists and turns without relying on overnight DNA tests.
Similar to other cop shows, probably, different and standing on its own, yes it does that too.
Really though, how many police shows are all that unique nowadays anyway (CSI and NCIS franchises) or the formulaic UK shows: Two unusual surnames for the title, a male/female lead, one of the two has some disturbing past that troubles them.......doesn't make them bad watching.
It's perfectly fine to watch TV for entertainment and not to be educated or enlightened, that's what real life is for. Brokenwood does that from an NZ viewpoint with a bit of brain engagement and if you don't think this sort of thing happens, you haven't read the papers for 40 years.
