Great concept, mixed end result
It was an interesting idea to push the idea of "The Act of Killing" a bit further, by entering a new side to the cruelty: Confronting a victims relative to those murderers.
Still, the end result was just weird. Some thoughts of mine:
-The movie structure was strange. The motivation of Adi was so randomly set up. How about some discussion with HIM first, about why he must do this, why he is risking his and his family's lie, how those hitmen actually agreed to this.
Instead we saw totally pointless recordings of his senile half-dead father, who had nothing to contribute to the movies subject. I felt really akward, why I need to watch this old mans suffering. Strange enough how the 44 year old protagonist could have a 100 year old mother and a 110(?) year old father. It was interesting to see Adi's child/wife, but overall it was also pointless to see him argue with his farting daughter. These moments didn't really make me feel closer to him
-Why confronting the uncle? He somewhat blamed him that he assisted the murders as a prison guard. How naive can he be, that he could've done anything in that situation?
-The Interviews: Most interesting parts of the movie, still, I felt there was no conclusion to them (same goes for the whole movie). He asked questions, they answered (sometimes blurry). Adi shows no reaction for 10 seconds. Next question. It didn't really felt like I'm watching an interview. Maybe the real talk wasn't like that, only the editing made it look like this. If so, it was a bad move, to sacrifice the flow of the talk to import some director's signature move art with the still images.
-Why do I have to read afterwards what the afterlife of Adi is? That he had to move away after production. This should've been more than clear for him already when they kept doing the interviews
