Not only do I love Sherlock and John and all the other characters, but I also love the cinematography. Every episode has at least one absolutely breath-taking shot. And "The Great Game" has by far probably my favorite shot ever, when the light filters in through the blown-out windows and settling dust. Knocks the wind out of me every time.
'But I could not rest, Watson, I could not sit quiet in my chair, if I thought that such a man as Professor Moriarty were walking the streets of London unchallenged.’ ~ The Final Problem by Sir Arthur Conan Doyle
