This reworking of the Sherlock Holmes legend is a marvelous, delightful adreneline rush which does not take itself too seriously - with some impressive repartee between Jude Law and Robert Downey, Jr. as well as cleverly written one-liners for many of the supporting actors. Not for Sir Arthur Conan Doyle purists, but for the rest of us, a refreshing new perspective on a most iconic and enduring literary figure. While Robert Downey, Jr. does not resemble any incarnation of Sherlock Holmes by any stretch of anyone's imagination, he acquits himself admirably; we believe him. My only quibble is the presentation of Irene Adler as a romantic interest, which she never was in any of Sir Arthur's stories. Regardless, five stars. See it!
And a must-see for a second time in a couple of days. Cameron's characters lacked the depth of his protagonists in "Titanic" but this isn't a drawback to watching the film. Cameron knows how to engage and entertain!
