Grant Hodges’s review published on Letterboxd:
Three Billboards Outside Ebbing, Missouri is one of those rare movies I appreciate more and more every time I revisit it. And despite some stellar performances, fantastic directing, and a great soundtrack, I think this appreciation can be narrowed down to one single thing - the screenplay. From the reveal of the movie's tragic backstory via the billboards to the nuance of each one of our leads (where no single one of them is the solitary voice of reason or good/bad), from the incredible balance of drama and levity to the absolute gut-punch that is Cheif Willoughby's death only half-way through the film's runtime, this thing is a masterpiece.
Yes, the movie has its flaws. That weirdly CG'd in deer is pretty jarring. And despite my appreciation of the film touching on many current social issues (especially in the police system), I do think relegating all minorities to the background roles probably wasn't the best move. Still, the film presents a shockingly accurate depiction of an American small town. And seeing as it is focused pretty much entirely on Mildred and Dixon's journeys to become better people, I think these flaws can be forgiven.
If you haven't seen Three Billboards, I urge you to watch it. I know I'm definitely not doing a good enough job selling it (because it's one of my all-time favorites and nothing I could say would do it justice). But I think if you watch it, you'll understand. Hell, maybe - just maybe - it'll become one of your favorites too.
