Which is something that does happen with sequels from time to time and is probably a result of how quickly the film was put into production following the success of the first film in 2009.
Picking up about a year later we find Dr Watson on the eve of his wedding and a Holmes who has become more and more intent on tracking down his nemesis Dr Moriarty. As a series of random and seemingly unrelated events are connected by Holmes, he soon realises the scale of Moriarity's true plans and must give everything he has to prevent disaster.
The key pairing of Robert Downey Jnr and Jude Law is central to the film here just as it was in the first, which is good because the film has a very sluggish and slow first hour as it drags itself together and starts to have anything resembling a plot to hand. However, once the trail begins then a solid enough action film emerges and manages to build to a quite well done conclusion at a famous location in Holmesian lore!
Of the new cast Jared Harris is a convincingly menacing Moriarty, channeling effective nonchalance as he casually informs Holmes of just what he will do to stop him, but Noomi Rapace is essentially wasted in a sidekick role that doesn't give her anything remotely major to do apart from serve as a female role in the film. Although Stephen Fry is also welcome as Holmes brother and intellectual and deductive match.
On Blu-ray the picture quality is very, very nice (Warner Bros always seem to be able to ensure their Blu-ray picture quality is always amongst the best around) especially in some of the big visual effects sequences such as the forest run. The extras however are fairly light. Basically you have an option to run the film concurrently with some behind the scenes featurettes while Robert Downey Jnr pops up in person from time to time to talk about the film in the same way that Guy Ritchie did on the Blu-ray of the first film. And then you can watch the featurettes separately. That's about it really. Not a great selection but not stuff that takes an age to go through.
I enjoyed it, but I do feel the first film was stronger and that if they make a third they need to up the game a little to avoid some of the sluggishness that afflicts this entry in the series.
