Robert Downey Jr. and Jude Law play London detectives Sherlock Holmes and Dr. John Watson, who captures the black magic follower Lord Blackwood (Mark Strong), but has somehow mysteriously returned to life after his hanging. Holmes is called on the case again as Blackwood is seeking exact revenge on him and the rest of London. Sherlock is also visited by former lover Irene Adler (Rachel McAdams), who has a secret agenda of her own.

This movie has some intense and thrilling action scenes, particular those involving Sherlock and Blackwood. However, the overall pace of the plot is slow and tends to drag the story and the supposed humor did not deliver. The acting was OK for the most part, but the chemistry between the character leads suffers a little, which didn't provide much development and charm. The music score, though, was pretty catchy, and the sceneries of Old England are very nice.

Overall, it's an average movie.
