"…the other half of the series takes place in what we’d call “the Heart Palace” of Martin Freeman’s Dr. John Watson. We see the crimes from Sherlock’s perspective, but we see Sherlock from Watson’s. Freeman’s Watson (like the original, a veteran of a war in Afghanistan) persuasively embodies Watson’s own appetite for risk-taking. He creates an intelligent, sometimes puckish, and often questioning foil to Cumberbatch’s brilliant brand of cheek. Most important, he communicates his empathy for a man who really does act, sometimes, like a sociopath."
