I love this show. In both this series and in Elementary the character of Watson becomes much more than the proverbial sidekick, and that makes the drama so much richer.
I do have a bone to pick with the episode based on The Hound of the Baskervilles, though. The resolution of the case rests on Sherlock interpreting the images his client described from his childhood experience. 1) Sherlock never actually saw those images and 2) secret CIA programs don’t print sweatshirts.
