“Father Stu” (*** out of four) was an agreeably done melodrama based on the true story of Stuart Long (Mark Wahlberg) who started out as a ruthless boxer and then suddenly found a higher calling in life as a priest even as severe health problems derailed his life. The type of film that is make-or-break based on its lead performance and Wahlberg once again shows his charisma and power and carries this movie whole-heartedly even through minor lulls. Mel Gibson is well-cast in a key role as Long’s loutish and alcoholic father and Malcolm McDowell has one of his better roles in years as a monsignor.
