Most of Sir Arthur Conan Doyle's stories in the Granada series hold true to the original. Sure maybe some of the dramatizations are over the top, still they stick to Sir Doyle's original story and allow Brett and Burke to give flesh to Sherlock Holmes and Dr. Watson.
Unfortunately the last vampyre (left lower case on purpose) was written so poorly with TV type scenes and situations that even Basil Rathbone would have been embarrassed to play Sherlock in. He__, even Huckleberry Hound would have been embarrassed.
Preserve the image of Brett and Burke doing an incredible job of bringing Holmes and Watson to life; do not watch this episode.
