Talk to those people who first saw films when they were silent, and they will tell you the experience was magic. The silent film had extraordinary powers to draw members of an audience into the story, and an equally potent capacity of make their imaginations work.

Some films experimented with players the 1915 film Regeneration, for example, by using real gangsters and streetwalkers, provided startling local color. Other films, particularly those of Thomas Ince, provided tragic endings as often as films by other companies supplied happy ones. Unfortunately, the vast majority of silent films survive today in inferior prints that no longer reflect the care that the original technicians put into them. The modern versions of silent films may appear jerky and flickery, but the vast picture palaces did not attract four to six thousand people a night by giving them eyestrain.
