Peter O’Toole is again the voice of the famous sleuth in this disappointing animated adaptation of the first Sherlock Holmes mystery.

The adaptation is faithful to the original novel’s structure (sadly, as it’s a somewhat bizarre one, and ripe for a more interesting interpretation), but loses any elements pertaining to Holmes and Watson’s first meeting. The animation seems more basic than the other entry in this particular series that I’ve seen, and O’Toole’s performance is flatter. The rest of the cast don’t fare any better. The story itself isn’t a bad one, but after being pleasantly surprised by The Sign of Four, I just found this to be disappointing.
