If you loved The Flock, try Infernal Affairs III
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Andrew Lau Wai-Keung, and they sit in Crime / Drama territory. If that's the register that drew you to The Flock, the second film will land in a comparable space — through a different lens.
What Infernal Affairs III is
You're a dirty cop in Hong Kong trying to bury your past. But a complex web of lies tightens. A mole hunt ensues. The original's moral inversions get a twist in this conclusion. It lingers on fractured identity.
