What Deadly Outlaw: Rekka is
Mount Fuji at dusk, a chrome pistol dropped in snow. A young enforcer kneels beside his mentor’s ruined face. Their trail of spilled whiskey and shell casings ends where a scarred father figure waits with a cleaver. Miike’s 2002 acid western where honor bleeds into neon and every bullet sings the blues.
