So many things that just don't add up

Rating: 4/10 (18 April 2018)

Billboards set ablaze but apparently the only thing that burned were the plastic wraps.....silly.
What was the purpose of the conversation with the priest? How did what happened to her daughter have anything to do with Catholic priests molesting alter boys? And in a small southern town, what was the likelihood the lead character was Catholic.....seemed agenda driven to me.
A cop beats up an innocent citizen and throws him out a window yet his only punishment was losing his job? How was he not immediately arrested and thrown in jail.....mind boggling.
A woman firebombs a police station and there is no investigation. The new cop sent to the town just accepts the statement of the local town dwarf and life goes on.....hard to believe.
Why did the stranger go into her shop if he had nothing to do with the murder? If this man was out of the country and had no association with the Sheriff why would he care about the billboards?......Illogical.
The movie was watchable until Woody Harrelson's character kills himself.....the movie dies at that point as well.
