This enjoyable feature does a good job of filming a creative, interesting story using G.K. Chesterton's "Father Brown" character. Alec Guinness is a very good realization of Father Brown, and Peter Finch provides him with a worthy foil. The story uses a good variety of interesting settings, with numerous interesting turns in the plot, and some good moments from the supporting cast.
What makes it more intriguing than the average crime/mystery movie is that from the start Father Brown is more interested in reforming the criminal than in punishing him. It leads to a story that has some of the same elements as a conventional crime film, but it also adds a creative dimension that makes it so much more interesting than the dreary, excessive spectacles of the present time that drown out any substance with undue amounts of violence and crudity.
The story could, of course, have easily become implausible and/or annoyingly moralistic, but thanks to Guinness's usual fine performance, and good direction from Robert Hamer, that is not at all the case. While there's nothing flashy here, it's an interesting and enjoyable little feature, and a nice change of pace.
