Jack Lemmon shines as Father Farley, a spineless priest who'll say anything to anyone if it makes his life easier. Through a series of circumstances, he has to face himself as a result of being "assigned" Mark Dolson as a deacon.
When I first watched this movie, I was disappointed by the ending, because it didn't seem to resolve the main issue (which concerns Mark Dolson). But eventually I realized that it issue was Father Farley, and his spinelessness, and Mark Dolson was merely the means by which Farley is brought to terms with himself.
My second favorite movie of all time.
