I, The Executioner - 1968 - 7/10
AKA - Minagoroshi no Reika // みな殺しの霊歌 / Requiem For A Massacre

The first murder was vicious.
The victim stripped, bound, gagged. Forced to write the names of the others.
By the second death, police suspected a serial killer.
Three other women meet. From fearful to dismissive. One wonders if deaths had to do with “that day”.
So do we. Yet the mystery of what and why is doled out in stages.
Camerawork is inspired throughout, from low ground angles to extreme closeups.
Makoto Satô is an intense, remorseless, deliverer of vengeance.
Gripping thriller, though the denouement … I dunno.
