There's something to be said for the quietness of this movie, a side effect of early talkies. The Dracula story has been adapted so many times that for any new adaption I watch its really all about those in-between moments. Here they're silent as the grave and brimming with a sort of eerie ritualism.
Dracula truly feels out of time, deeply unknowable and with his own agenda. Something primordial dressed in aristocrat's clothing. Every frame threatens to be subsumed by darkness, the ancient darkness from which vampires sprung. Get your crucifix and wolfsbane ready!
