Wired has an article featuring their choice of the best Sherlock Holmes adaptations, but they loosely include other characters that are only derived from Holmes. This is good in the instance of Justin Playfair in They Might Be Giants, but is less so in the case of Batman. I only complain because it would have provided more room to include other Holmes adaptations like the Russian TV series or the Ronald Howard Holmes.
Alan Sepinwall also has a review of Sherlock, and he also mentions other modern derivative TV detectives. I hope everyone gets a chance to enjoy this show after the long wait for it to get to America.
