We all really enjoyed it, much more than I'd expected. Though I did have something of a chicken or egg thing going because it really reminded me more of House and Wilson than any prior Holmes shows/movies I've seen in the past. So that was rather interesting.
Wasn't too sure about Mary in the beginning, but she'd grown on me by the end, and I loved Irene! It was nice to have a more prominent female presence than is usual in a Holmes project.
RDJ was very good in the role I thought, as well as the actor who played Watson (whose name escapes me currently). Overall, a thumbs up from all three of us and definitely a DVD purchase when it comes out.
