Asked about the trailer for Elementary, Steven Moffat observed:
"What we did with our Sherlock was just take it from Victorian times into modern day. They’ve got three big changes: it’s Sherlock Holmes in America, it’s Sherlock Holmes updated and it’s Sherlock Holmes with a female Watson. I wonder if he’s Sherlock Holmes in any sense other than he’s called Sherlock Holmes. It’s almost like they should have made Watson a woman but kept the show in Victorian times. Actually... that would actually be quite interesting."
How much is too much? I've spoken about this before, but yes, a change-one-thing spin is likely to be closer than changing three or more things.
And now I'm imagining him making a bunch of different Sherlock Holmes shows instead of just one.
