As a big fan of Jeremy Brett's Holmes, I really liked this Sherlock Holmes adaptation. I have liked a lot of the feature length adaptations, this, Hound of the Baskervilles and my personal favourite Sign of Four being the best in my opinion.
I agree it is slow at times, but I still liked it because it was well acted, had an interesting story and had excellent period detail. The story it is based on isn't a favourite admittedly, but it was a good enough read, however I do think I prefer this adaptation. As you would expect the period detail, sets, photography, costumes and scenery are exceptional and the music is haunting and beautiful. The story is an interesting and involving one with a touch of regret and melancholy about it, the script is well written and sophisticated, the direction is good and the acting is very good.
Jeremy Brett and Edward Hardwicke are brilliant as Holmes and Watson, no surprise they always are, Serena Gordon is a beautiful, alluring and sympathetic Eva, Sophie Thompson is lovely as Agatha and Robert Hardy is truly excellent as the villain of the piece, and a notorious villain he is too. Overall, excellent in almost every aspect, definitely recommended. 9/10 Bethany Cox
