Actually the Focus on the Family review was pretty positive.
They note the profanity because they know parents want to know these things in deciding whether the film is appropriate for their children.
Also, one interesting note ... Sliney himself says that he was asked to exaggerate the profanity ... so it wasn't strictly "realism":
Sliney did note, however, one thing that was exaggerated for the film: profanity. "They asked me to swear, which I customarily don't do. ... I wanted on that day to be calm and authoritative for all the people on the floor. In a stressful situation, they don't want to see the person in charge getting excited." That added vulgarity is perhaps the only obvious box-office concession in a story that in most other ways is not typical Tinseltown fare.
Didn't know about Sliney and the language.
