This is an excellent melodrama, with a fine performance by Mary Pickford and much more besides. The settings, characters, and photography create an interesting and memorable world in which the adventures of Molly (Pickford) and the orphans take place, in a story with plenty of drama and suspense.
Molly was an ideal role for Pickford, who could make such a character appealing and very sympathetic without going overboard. Though most of the film is quite serious, she also makes good use of the occasional comic moments. The settings in the swamp and on the farm run by the vile Grimes are nicely conceived and created. The sets are filled with careful atmospheric detail, and the photography is excellent. The Grimes family are very good villains, and Gustav von Seyffertitz gives a fine portrayal of the nasty farmer.
There is plenty of action and there are some fine scenes, leading up to an excellent suspense sequence in the swamp, with plenty of thrills and excitement. The only thing that keeps it from being a nearly perfect film is that the last part does drag on just a bit, becoming rather anticlimactic, and it would have been an even better movie if it were maybe 5-10 minutes shorter. But that doesn't change the fact that overall it's great fun to watch.
If you are a fan of silent melodramas, make sure to see "Sparrows" if you get the chance.
