In 2009 Sherlock Holmes was re-imagined by Guy Ritchie as an ass- kicking and mentally unstable private investigator with a weakness for a variety of mind-altering substances. Played by Robert Downey Jr., Holmes was Iron Man without the vast fortune, super-suit and fashionable beard, but with the same genius-level intellect, capable of predicting the exact outcome of a fight with a foe before the first punch is thrown. Though heavily compromised by Ritchie's sledgehammer subtlety and love for annoying Cockney geezers, it was still an entertaining take on an extremely familiar character, with Downey Jr. at his twitchy best and demonstrating a convincing English accent.

A Game of Shadows, the bloated sequel rushed into production after the international success of its predecessor, turns the doctor from idiosyncratic eccentric to a babbling pantomime. When we meet Holmes, he is rescuing his flame Irene Adler (Rachel McAdams) from a bomb intended for somebody else. The package was given to her by the scheming Professor Moriarty (Jared Harris), and after her next meeting with him, she disappears. On the eve of his wedding, Dr. Watson (Jude Law) arrives at Baker Street to find Holmes deep into investigating a splurge of seemingly unrelated murders and business acquisitions linked to Moriarty, and at Watson's bachelor party, the two encounter a gypsy woman named Simza (Noomi Rapace), the intended recipient of the letter that accompanied the bomb.

Without any sign of the storytelling flair of the books, A Game of Shadows becomes little more than a series of punch-ups, shoot-outs and inane exchanges between Holmes and his trusted Watson. At one point, the heroes are fired at by an increasingly ridiculous arsenal of machine guns as trees shatter and fireballs explode around them in ultra slo-mo. Any resemblance to one of literatures most beloved characters is lost, and it feels instead like you're watching a movie about The Transporter's British granddad, albeit with a touch more style. Mad Men's Harris is impressive as Holmes's most challenging foe, but Rapace's character is so redundant that she is reduced to just a pretty face for the poster. Shockingly, the main problem is Downey Jr., whose hyperactive shtick is as tiresome as the plot he is caught up in.
