The problem with this interpretation is that it seems a disconnected story from the canon of Sherlock Holmes stories. While it has a fascinating (though not original) idea of having a younger Sherlock Holmes who is the polar opposite of the character we came to know in the book, it never fully develops this.
Richard E Grant plays a good role, as Mycroft. To the reviewer who stated that Mycroft never appeared in the stories, I direct you to the 'Greek Interpreter' and 'The Bruce-Partington Plans'. Watson may well be the person who Holmes accuses in the stories of making things up - he is a police official - not in Afghanistan. The idea that Moriarty invents heroin is a bit much.
In all, the story was good, but the film could have been better.
