"Nerven" or "Nerves" is a German black-and-white film from 1919, so this one will already have its 100th anniversary 3 years from now. And if you take a look at the year when this was made, it is easy to understand that this is still a silent film, namely very briefly after World War I. The writer and director is Robert Reinert and he is not too known anymore today compared to some other German (language) silent filmmakers like Murnau, Lang or Pabst. Same can be said about the cast here. Despite having seen many films from that era, I cannot say I am familiar with any of the names credited there. In terms of plot and story, I would say this is not one of the best or worst from the genre. People who love slightly scary very old silent films will maybe have a good time watching, but I did not really. I think at 110 minutes, so not much under 2 hours, it was way too long for its own good and I lost interest quickly. That's why overall I give it a thumbs down. Not recommended.
