About
You’ll likely enjoy this tense noir crime thriller if you like fast-paced redemption plots with a character-driven, dementia-focused struggle; Not for you if dark, mentally unraveling stories like The Father or Sleeping Dogs feel too heavy.
Pros: intense ticking-clock tension; powerful lead performance; noir crime drama tone | Cons: slow start; some dialogue feels off; budget/production uneven
