There's plenty of evidence that Americans have an appetite for “cleaned-up” movies. Mainstream films with minimum levels of objectionable content are often impressive box office performers; Beauty and the Beast is still the No. 1 highest grossing film in America so far this year by a healthy margin (and the relatively tame Wonder Woman is in the second spot). The Hallmark Movie Channel, which airs boilerplate clean films, often posts very high ratings, especially around the holidays, when families spend time together. And the faith-based movie market — of which the most marked indicator is a lack of any “objectionable” content — continues to grow, often raking in huge numbers at the box office despite tepid critical reception.
