“Three Billboards Outside Ebbing, Missouri” is a difficult movie. Uncomfortable as it is, it’s a film that should be seen, and can be viewed as a cautionary tale for all, not only residents of Ebbing, nor billboard companies.

“Three Billboards” got four Golden Globe Awards Jan. 7: drama; screenplay (Martin McDonagh, who directed); lead actress, drama (Frances McDormand); and supporting actor, drama (Sam Rockwell); received People’s Choice Award at the 2017 Toronto International Film Festival; is an American Film Institute Top 10 film of 2017, and a multi-category Oscar nominee contender.

This movie review won’t reveal much of the grueling and gruesome plot because there are so many unpredictable twists and turns on the road to and past the “Three Billboards” (one reason it deserved a screenplay kudo).

Suffice it to state, there are three billboards rented by Mildred (Frances McDormand), who has placed on them huge accusatory statements intended to shame Ebbing Sheriff Bill Willoughby (Woody Harrelson in another fine performance) concerning the unsolved rape-murder case of her daughter, Pamela (Kerry Condon). The chief is sympathetic to Mildred’s plight. Ebbing police officer Jason Dixon (Sam Rockwell) becomes Mildred’s nemesis.

Each character has a back story, edgily etched in behavior, dialogue and attitude that will make you want to run screaming from the theater before the film concludes. Mildred has unresolved guilt concerning her daughter. She taunts her son, Robbie (Lucas Hedges). The chief is battling cancer.

Director McDonagh (“Seven Psychopaths,” 2012; Oscar screenplay nominee, “In Bruges,” 2008) struck a nerve, a minefield and hit gold in this Midwestern gothic tale of revenge gone horribly awry (can it go any other way?).

McDormand is at her deer-in-headlights best, with nary a smile and a mouth spewing profanities rivaling Eagles NFL players in the Linc field tunnel before the Falcons’ playoff game.

Rockwell portrays a repugnant racist so convincingly the role has been attacked by some.

Mildred seems to have taken to heart the quote from a page in French author Eugène Sue’s novel, “Memoirs of Matilda,” which was translated into English by D.G. Osbourne and published in 1846: “And then revenge is very good eaten cold, as the vulgar say.”

Keep your eye on “Three Billboards.” You won’t be rewarded with a Burma Shave sequential jingle on highway signs, but you may discover a redemptive quality. And that’s quite a roadside attraction.
