If you loved Massacre Gun, try Retaliation
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 Yasuharu Hasebe, and they sit in Action / Crime territory. If that's the register that drew you to Massacre Gun, the second film will land in a comparable space — through a different lens.
What Retaliation is
You walk out of prison into a gangless vacuum. Another syndicate offers rank for wiping out a rival family but their promises dissolve fast. Hasebe frames loyalty as a currency that bleeds out fast.
