The movie is well worth seeing and sticking out to the end... in places the implied super-natural element and the action (there is a lot of physical action) might definitely annoy some fans of Sherlock Holmes stories - in fact a few people did walk out of my cinema in annoyance - but I urge you - if you start getting annoyed to with-hold judgement until end of the film - it turns out that does respect reason and contains enough of a detailed intellectual construction to satisfy discerning intellects- there are lots of carefully constructed clues embedded in the film. Great fun!
