This is a must buy! One of the finest sequels and movies i have ever seen. Though the first is still amazing this surpasses it by a long shot! Script, story, performances, everything is spot on. I honestly can't fault a single thing about it. Very clever and Sherlock and Moriarty's chemistry are the finest hero-villein since Joker and Batman. Fantastic effects and some of the most jaw droppingly exciting and impressive action sequences i have layed eyes on. Bigger, better than anything Sherlock can deliver, which is why i think if they do a third it won't be better than this.
