Yet silent dramas themselves are now an acquired taste. They feel lecturing and old-fashioned. The comedies seem fresher; they work for modern audiences much as they must have in the 1920s. If the measure of a comedy is its ability to make you laugh, then the measure of a drama is its ability to move you—why do silent dramas now struggle to do this?
Such a question needs more than a thousand words, but I believe the absence of speech can be quickly blamed. Without speech, a director must convey information either through the actors’ pantomime or intertitles (word cards), along with pictures of signs, telegrams and letters. This is a balancing act, because pantomime expresses emotion better than precise information, while intertitles, if over-used, make viewing tedious. As a result, most successful silent films have simple plots, exploring common themes requiring little explanation.
With simple plots come simple characters. Silent characters are often archetypes (hoodlum, girl-next-door, bully, fool), and can proceed through the movie quite plausibly without much development. Nevertheless, silent actors put tremendous work into these roles; one of the joys of watching silent films is seeing the humanity imbued into a being with no name, odd clothes, and perhaps a singular goal: win the girl’s love; make friends; get a job.
However, an archetype’s dramatic power relies on the viewer’s ability to relate to it—that is, to believe the archetype is drawn from life. This is crucial if the viewer is expected to take a further step and actually empathize with the character. I argue that to empathize with an archetype is really to feel empathy for the social element that archetype represents.
Some archetypes still work pretty well. Consider the social ill of poverty: Silent drama’s Orphans, Beggars, and Labourers are all emblems of Poverty, and while we may possess only the barest of backstories about these characters, our belief in the regrettability of poverty and the suffering it causes allows us to fill in the rest. When archetypes fail, it is because the viewer’s conception of the world cannot be reconciled with them. If they no longer represent universal truths (or even widely held assumptions), the suffering the actor exhibits can seem overwrought, silly, or even obnoxious. This is ever more likely as years pass, societies evolve, and the archetypes remain fixed.

Yes, it’s possible to contextualize these characters and understand why they act as they do; it’s certainly possible to dislike the ‘fallen’ woman, even if her only real crime, by today’s standards, is sexual liberation. However, it is very difficult to place oneself so fully into someone else’s shoes that you can be hurt or offended by something that today seems backward or trivial.

Silent characters are given life through facial expression and gesture. They speak, too; but we can’t hear it, only see it, so the issue is usually not what they’re saying, but rather, how they feel as they say it. The relationship between character and viewer is therefore an emotional one, with the film relying on a shared value system to answer certain questions in advance. That assumption cannot always be made today.
