Really looking forwards to this one. I have some issues with Sherlock (the show) in that it goes a little far off-source and takes Holmes in a direction that Sir Arthur probably wouldn't have recognized, but I've still watched most of it. But I'd be completely willing to forgive that if the producers give us an episode that's as much about Victorian London as the main show is of modern-day London. Because one of the things I really like about Sherlock is the obvious affection for its setting; the show gives a real flavour of place, if you get my drift.
