“Three Billboards Outside Ebbing, Missouri” (** out of four) was a tepid melodrama about an older mother (Frances McDormand) whose frustration with the local law enforcement and their failure to solve her daughter’s murder leads her to create 3 local billboards which sends a rippling effect through the community and antagonizes the local sherriff (Woody Harrelson). Both McDormand and Harrelson are excellent as usual but story meanders and is limited in its emotional power. Many critics thought highly of this so you may want to judge for yourself.
