About Sherlock

Sherlock Holmes and Dr. John Watson's adventures in 21st Century London. A thrilling, funny, fast-paced contemporary reimagining of the Arthur Conan Doyle classic.

How to get through Sherlock faster

  • Skip the intro. Roughly a minute and a quarter per episode adds up to about 15 minutes across the whole run.
  • Bump the speed. At 1.25× the total drops to 14.4 hours; at 1.5× it's 12 hours.
  • Watch with a comment section. A running conversation pinned to each moment makes long stretches feel shorter, and it's the reason TalkAbtIT exists.
