If you like warm feelings and inspirational plots, especially if you are religious, you will love this film. If you prefer PG-13 and above, don't bother. This is solid family entertainment. It has superb acting and writing, and it is very heart warming without being corny or maudlin. Bogart is at his best type cast in his standard role of a cynic from the school of hard knocks who, when put to the test, shows himself to have a heart of gold underneath it all. The extreme poverty and ignorance of Chinese rural people at this time, as well as the very successful inroads made by Catholic missionaries there during this period are accurately portrayed.
