This movie promises to be a fun ‘buddy cop’ style action flick, but is in fact a tense, slow-burn serial killer thriller. Of course there are a few action scenes, including the final showdown, and plenty of Stallone being Stallone but its mainstay is gritty crime thriller.
Closest comparison: It’s like Tango & Cash by way of Blue Steel.
Setting: Buddy Cop
Plot: Serial Killer
Tone: Horror/Thriller
