Unless you want to see a bunch of people flapping their gums soundlessly while someone tinkles on a piano, or you are a Holmes completist, you would probably be better off watching one of the many later versions of The Hound of the Baskervilles (I recommend the definitive 1939 talkie starring Basil Rathbone). That's not to say that this silent film is entirely worthless but so much of what makes Sherlock Holmes great is the famous detective's way with words, particularly his banter with best bud Watson. Without that repartee, the film is lacking.
Thought lost for many years, an incomplete tape of Richard Oswald's 1929 The Hound of the Baskervilles was eventually discovered in the basement of a church in Poland and digitally restored, with stills replacing the missing footage. It's a fairly faithful adaptation of Conan Doyle's novel, with decent production design, the Baskerville manor and the windswept moors being particularly impressive, and the ending delivers some excitement, as Holmes becomes trapped in a tunnel that is rapidly filling up with water, but the bulk of the film is unevenly paced (definitely not helped by the missing scenes). The film was a commercial failure on its original release, probably because it came out just as sound was coming in.
