This one's a bit of a head-scratcher. - it's a example of that odd 1980's era of faux film-noir that tries to emulate classic 1040's-50's crime flicks - tough guy cops, tough-guy gals, B&W tonality, snappy cop repartee over gruesome butchered bodies, etc - but just doesn't have the same authenticity - somehow 80's stuff too self-aware and facilely stylistic.
Leslie Ann Warren as the female-at-risk lead is a questionable casting choice - Leslie's always a trooper as an actor and does her part well - but she's just not the tough gal "type" - but there are a lot of other fun early career cameo appearances - Chris Noth (Sex & the City), Harvey Fierstein as a recurrent grim comic relief as a street guy, etc.
The thing is supposed to be occurring in 1980's gritty grimy version of the Big Apple (i.e., pre-Disney-ized Times Square), but apparently was actually filmed in Toronto, so, just like the classic film-noir wanna-be-ism, the whole ambience of the settings just don't quite ring true.
Nonetheless, it's not a waste of time to watch; as mentioned, Leslie Ann Warren is quite OK, just not the type for the film noir genre - I mean, let's face it, the gal-at-risk has gotta be a platinum blonde hooving at least 5 packs a day and she's not & doesn't - and the basic story line does have some clever takes on updating the 40/50's crime noirs. Additionally most all of the male actors are good in their standard crime noir roles - cop investigator, wise-guy DA, chronically annoyed supervisory lieutenant, sleazy-voiced bad guy perp leaving deranged phone messages - I think because they're not trying too hard and just rolling with the irony.
So, if you just want something lite - crime noir "lite", that is - this wouldn't be the worst thing to spend an hour and a half watching. :-)
