The first impression of the film was bit abstract. First of all there are few dialogues and most of them are expressed by actions and facial expressions. I think it is the way to be easier in directing the film, it might be hard to handle a pile of dialogues, also it would give more room to edit the film.
Then, I think casting did very well too, the two young girls that they don’t need to have much conversation but just playing together in the park that could illustrate they are good friends in the beginning of the film. Also, the woman crying at the last scene was doing very well also. The camera movement would be the best part of the film in my opinion. The handheld shots and the point of view shots (POV) could make the film become artistic and abstract. Especially the perspective of the girl who is on the roundabout that the best shot in the film. Also, the close up shots of both girls could contribute the atmosphere of the film.
