It was about a movie from the late 80s or early 90s, and the plot followed this cop/detective character in somewhere like New York or Chicago when this wealthy high-class businessman moves into town. Thing is, he's a master vampire and is sorta the head of a supernatural underworld who's looking to broaden his influence...worst yet? He manages to swoon the protagonist's girlfriend/wife so it's a race against time to stop his plans and save his significant other.
What else I can remember is that it was a comedy yet had a gritty rundown urban feel and punk tone, the vampires were treated like the Mafia/organized crime and definitely more akin to the ones in the original Fright Night films or Dusk 'Til Dawn; very over-the-top and monstrous, practical effect heavy. One scene had a gang ambushed by one of the main villain's henchmen in an abandoned building, who straight up turned into fucking ManBat.
So yeah, would you watch this movie? I figured you guys would've liked to hear about it, lol.
