About
You’ll likely enjoy this tense undercover crime mystery if you like spy-versus-spy games and fast, high-stakes intrigue; Not for you if you want a calmer, straightforward thriller like Running Out of Time or The Killer.
Pros: engaging cat-and-mouse; solid crime mystery; strong performances | Cons: stylized/tension choices; confusing pacing; over-dramatized music
