Who's your favourite Sherlock Holmes? Benedict Cumberbatch or Rob Downey Jr.? Jonny Lee Miller or Jeremy Brett? It's so hard to choose, so spare a thought for poor Dr Watson - faced with so many Sherlocks old and new, what will he do? Who's so the wrong height? Who's too black and white? Who's too pale of face? Who's in the wrong place? Who's the right Sherlock in Doc Watson's view? And is Watson's Sherlock the Sherlock for you?
