Random Sherlock Holmes-Related Thought of the Day

If you're going to do steampunk-y Holmes, or fantasy Holmes, or vampire Holmes, or literary mashup Holmes (Alice in Dr. Jekyll's Laboratory Meets Sherlock Holmes), or whatever, please don't do so by half measures.  Standard-issue Holmes pastiche with a light dollop of steampunk/fantasy/vampires/mashup/whatever makes zero sense in terms of fictional world-building.
