I love Arthur Conan Doyles Sherlock Holmes, hated the Hollywood movies that recently came out (although the actors were good) and now I have seen New Sherlock Holmes (don't know if it is the series real name) and I must say that it is amazing! It's better than the books, better than Agatha Christie, better than anything I have seen for the past two days! It reminds me of House.MD except that you don't have to be a doctor to understand everything that is happening. If you enjoy good TV and/or Death Note, Sherlock Holmes, Poirot, mrs Marple and everything detective related then this is your show. It is emotional, has cool action, good actors and characters... What more do you need?
By the way, Doctor Watson is played by the actor who will play Bilbo in the upcoming hobbit movie (forgot his name)!
