This was one of those movies that never quite grabbed me. It did have rare moments of requiring an emotional investment, but I was distracted by the self-conscious underplay by Mark Wahlberg. He achieved what he was going for, but at a price. He did not seem to care very much about anything. If an actor tries to duplicate a non-expressive person and the actor is in real life quite expressive, he needs to combine more of who he is and not try to duplicate the real life character. I wonder if the people of Lowell, Mass think this film did them justice. The clip at the end, where the real brothers are caught being themselves, somehow seemed more entertaining than the movie.
This movie is best for someone not familiar with Holmes or Watson either in literature or in the many move depictions. Once adjusted to the fact that Sherlock smokes a Popeye pipe instead of his signature one and no deerstalker hat, there still was the issue of Watson being such wild, weapon-wielding, tough guy with a chick in tow. Sherlock also likes to beat people up and dislocate jaws-scientifically planned. It's an action-adventure like so many others. The narrative become secondary to the fighting and action. Worse, all of Sherlock's brilliant deductions came in the manner of voice over and quick flash backs.
