In many ways, the character is identical to Tony Stark in the Iron Man films. Holmes and Stark are both geniuses. Holmes and Stark are both eccentric to the point of madness. Holmes' sidekick, Dr. John Watson (Jude Law), is the nagging voice of sanity, much the same as Pepper Potts in the Iron Man films. Or maybe the robot butler Jarvis is the one who fulfils that role.
The setting is perfect. Guy Ritchie was the best choice for director. He has a passionate love for London, and his dull coloured portrayal of the streets has a morbid beauty. I need to watch the film again. This is a film I'd like to sit and watch with someone else. It's a shame Kaylena lives so far away.
