There is a reason audiences prefer "talkies." Movies are about communication, and speech is a mode of communication. It loses so much to reduce conversations to a few written lines across the screen. And modern-day audiences aren't good at being still and silent -- there's the noise of shuffling, chewing, whispering, paper crunching, etc. The story is short & simple, but seems way drawn out when not conveyed by sound. At the end the viewer understands why the film was deprived of sound, but it still felt like it had been a long period of deprivation.
