I just saw Sherlock Holmes - Game of Shadows. Another stellar outing for Robert Downey Jr. Several others who have seen it say they like it better than the first. I was so impressed by the first one, I'm not sure I agree with them. But it definitely is well done.
I loved the first but have yet to catch the second but will do so soon. If you enjoy the whole Holmes thing you might want to check out the new BBC version. Puts Holmes and Watson in a modern setting. I found it on Netflix, but think that PBS ran it as part of the Masterpiece Theatre series. I found it very enjoyable, there is just the one season thus far a total of three made for telly films.
