One of the previews that preceded this movie was a trailer for "Hot Tub Time Machine", how apropos I thought after viewing this rendition of Sherlock Holmes. It appears Guy Ritchie has brought 21st Century hip actors (Downy, Law, McAdams et al) and transported them back to Victorian era London. A fun ride yes! However as someone who has been enamored with the Great Detective from childhood, this depiction pays more homage to Madonna, than it does Doyle. Cinematography and sets are wonderful, the feeling of that London of long ago is expertly captured here. Sad that the characters and dialog could not have been set in that time as well. Bottom line, if you want to see Ironman stalk Moriarty, this is your flick. If you want to remain true to the Cannon and immerse yourself in England of the latter part of the 19th Century, I suggest you purchase or rent any of the Granada TV produced Sherlock Holmes videos, with Jeremy Brett and David Burke.
