"The Love Light" has some very good material and gives Mary Pickford a good vehicle for displaying her range of talents. The story also is often compelling, in its look at the ways that World War I affects the lives of the inhabitants of a small Italian town. But it also has some flaws in the story and character development that detract from its effectiveness. It's a good movie, but not one of Pickford's best features.
The first part of the story is a light-hearted introduction to the town and its residents. Bit-by-bit, the war begins to affect their lives, until the tone of the movie has become quite serious. This part is done very well, with good writing and craftsmanship, and it is effective. Both the setting and characters are also very believable, helped by some very good photography. The main part of the movie, as things get more complicated, has some compelling moments, but it is hampered by having too many implausible developments that make it seem forced at times. Another difficulty is that Pickford's character sometimes makes rather foolish decisions and behaves in ways that just don't ring true with the bright, resourceful character that she has established. This and other problems detract somewhat from the emotional impact of some of the key developments.
It thus ends up being a cut below some of Pickford's other melodramas. But it's still a movie worth seeing for its strengths. Because it starts with a good foundation, it holds up fairly well despite its flaws.
