Left-leaning critic Rainer's review of "The Assassins"

There were various positive and negative reviews, but ultimately, they all boiled down to one core point.
They're saying, "Why not just reach a definitive conclusion that Park Chung-hee killed Yuk Young-soo?"
"Director, if you were going to make the film in a propaganda style, why not just commit to it fully?"
"You structured the entire film as if Park Chung-hee were the killer, only to make the ending look 'open-ended' as if to say, 'I'm not quite sure~~~~'—it feels like a cowardly way of escaping responsibility."
The nuance is: "If you're going to do propaganda, just do it! If not, don't!"
The critic gave it a harsh 4 out of 10, stating that they would have actually been more generous if the film had simply concluded that Park Chung-hee was the killer.
