Traditional Roman Catholics seem to suggest a pass on the films overly human depiction of Augustine. However, it has 4.5 stars on Amazon.com, and that is definitely positive. A more contemporary writer Brandon Vogt recommends the film without reservation:
In the end, Restless Heart is the most epic saint biography ever produced.The film stands above the recent flow of sappy, low-budget Christian films and is more in line with The Passion of the Christ. With gifted acting, a moving score, and masterful screenwriting, it breathes life into three of the Church’s greatest and most iconic saints: Augustine, Ambrose, and Monica.
