If you loved A Flame at the Pier, try Samurai Spy
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 Masahiro Shinoda, and they both carry the outsider, slow burn mood tags, and they sit in Drama territory. If that's the register that drew you to A Flame at the Pier, the second film will land in a comparable space — through a different lens.

What Samurai Spy is
You're a samurai spy in feudal Japan, sick of bloodshed. But a defection throws the land into chaos. You pursue the traitor, while a hooded figure dogs both your paths. Shinoda's camera transforms chanbara action into a paranoid art. The film leaves you unsettled.
