First They Killed My Father

I saw this in Olympic Stadium earlier this year. The sets and costumes were terrific, as was the cinematography. I wasn't a big fan of the book that it was based on, but it was apparent that a lot of effort had gone into making the film adaptation historically accurate. The film is deliberately understated, and rather than showing much violence or gore, it instead has this implicit threat running below the surface. It's definitely worth seeing!
