The film does a real tight focus, in that it largely follows a group of low-rent gangsters selling forged movie tickets who became one of the more notorious death squad during the years of the progroms. These guys are old men now, never suffered any consequences, and are still considered heroes - happily bragging about the people they killed, re-enacting how they executed people while mugging to the camera. The film deals with the self-conscious amnesia of a country unable or unwilling to confront its trauma, the horror of your neighbours being the people who murdered your family, the performativity of violence. It doesn't do a deep dive into the broader ideology of the events - for that I'd recommend The Jakarta Method, which gives a more thorough context.
