Frances McDormand is superb as Mildred, the mother of a teenager that has been killed seven months prior. The investigation seems to have gotten stuck and Louise rents three billboards to ask the police about the state of affairs. The local chief is Willoughby (an also great Woody Harrelson) who has his own problems.
The film is presented as a dark comedy, but in my opinion it is a heavy drama with some dark humor. The film shows how Louise’s actions divide a small community. Both ‘sides’ have their points and both ‘sides’ have their drama. The situation derails quite a bit leading to interesting scenes and more drama.
A very good film with great acting.
