It’s brilliant. It’s an interesting thing to re-examine it in the 21st century because two bachelors of a certain age living together, questions get asked, or even answered by some people with supposition, but it’s um.. It’s a beautiful thing, you know. It’s a very real thing. I think Holmes is quite an extraordinary character, and I think Watson is, too, but he comes from a world that we recognize. He’s a returning, traumatized doctor, soldiering doctor, from Afghanistan. So he’s very real. He’s sort of the audience, the every man, even though he’s seen extraordinary things which have traumatized him, and also is in need of danger and action. And, hence, is drawn like a moth to the flame, to Sherlock. And I think what they discover through each other is that they absolutely need each other. It’s the idea that he’s the grounding anchor to this rather ethereal, other-worldly, slightly.. bombastic character. He brings him to Earth.
