You know, I was wondering about that. I just finished the series with him, and I noticed a lot of his actions were very similar to Benedict's. It was beautifully acted and my favorite version of Sherlock of 1880's. Benedict's is my favorite of now.
AAH! Ahaha yeah! He's brilliant! He had bipolar in real life, so he brought that and his obsessive nature into the role of Holmes. : ) He's kinda the one that made Holmes the "crazy, unpredictable genius" character he is today. And I love it! XD
