This is a nice review with some good analysis.
'Sherlock has depths and neuroses that are not only unexplored - he refuses to go near them, creating one of then, creating one of the most intriguing and tightly coiled men on screen today. For all his brilliance he is an emotional mess and Cumberbatch let's us glimpse the fact of all that messiness without letting Sherlock drop his brittle defensive guise to reveal the swirling emotions underneath... Sherlock is a great character, hugely flawed and irresistibly heroic. '
'McGuigan's direction is wonderfully stylish...'

It also mentions that Benedict and Dnny Boyle are considering taking Frankenstein to the New York stage.
