That's exactly right, Mara, and I find the attitude of the, er, "more traditional" Sherlockians rather odd. I mean, if the truth be known, the Holmes stories were speculative fiction, which eventually became the science fiction, fantasy, and horror genres of our modern day. The Holmes stories have more than a touch of the horror element, and a substantial amount of science fiction too.
ETA: I have to admit though, I did love the Jeremy Brett series, just to SEE the stories done period, and PROPERLY period. He is my favorite "period" Holmes. I think Cumberbatch is my favorite "updated" Holmes as portrayed. I'd love for him to do my Holmes stories if they ever get filmed. Eh bueno.
