its got a lot of action in it, which is why I want to see it too! Sherlock Holmes is traditionally lacking in action, and this seems like an interesting twist. And you'd never think Guy Ritchie directed it!
It was a very well done movie. The cinematics and special effects are awesome, the plot compelling--despite starting out slow, it really picks up in the second half of the movie. I'd say see it.
