And this is exactly where SherlockBBC Season 3 went all wrong:
"Immediately as an actor I wanted to understand who [Sherlock] was, what his parents were," [Cumberbatch] adds. "These were questions I asked ... I wanted to understand. [Moffat] was just talking about, 'Can't this guy just be good at what he does and he's your age and he looks like you and he's doing his thing?' And I went, 'No, no Steven, there's a process I've got to go through. I've got to understand how I became this person.' "
More Freudian stuff.
