First the top level, conceptual stuff. It works. Themes like grief and retribution without a vengeance plot could easily clash but here they converge without effort. Very good use of two purposes of photography that are opposites in intention but identical in power; both the secret of the atrocity and the exposed secrets of the tabloid rags relate father to son immediately and convey a sense of duty to the latter powerfully.
So much was established before a word was spoken. Evocative use of colour and mise en scene (the old man's apartment, the exteriors of the housing commission tower and the luxury apartment complex etc. Some dialogue scenes felt too expository and came off stilted for me (the confrontations between George and Eva). Contrasting with this, the dialogue between George and his boss warmed things up with humour. The monologue of George's mother was emotive, well performed and shot with a clear eye to the depth of its meaning.
I enjoyed the electronic score. The final stretch which laid down a slight drone so quiet it was almost imperceptible was exactly what was needed. A mainstream composer would have drowned it with a string section. The restraint shown with these elements reveals a clear respect for the material. That's why it didn't feel a second longer than it should have.Good luck in L.A., Tatiana. Break a sprocket!
