The style of animation used has a realistic quality to it and everything is very detailed, possibly to help push the fact that it was based on real events. At the end of the film the animation turns to some horrific real footage of the massacre, with the camera zooming and focusing onto the faces of the dead, which was quite difficult to watch.
The opening scene where a vicious pack of dogs is tearing through the streets is one of the parts that really sticks in my mind. I thought the power of the dogs and the fear that they inspired was conveyed brilliantly by the differing types of shot and the contrast between the darkness of the streets and the unnatural yellow sky immediately gave you an unsettled feeling, setting you up for the rest of the film.
I found this film really interesting, both visually and from a narrative point and I am now looking forward to more screenings.
