This was a silent film, and it had a score of a piano to accompany the film, but there was no voices none-the-less. Surprisingly there was a lot of dialogue. The characters would often have a whole screen full of text, but it was done in a way that wasn't as annoying as it would sound. The background for the text was very styled and really matched the tone of the movie. At no point was I ever confused about who was saying what to who.
Another very interesting thing was this movie was both in black and white and techni-color. The black and white parts of the film were when they were in the boarding school or in the city, and the techni-color (which is a pseudo color, mostly focusing on the color red) was shown in the Native American village. While the movie was switching between these two the entire film, it was not a big shock and it flowed between the two very naturally. It never felt like watching two different movies edited together.
Overall, this was the best black/white/silent film I have seen. The story had its points and it also had points that were evident of its time.
