There was no element of a whodunnit and the howdunnit didn't really play a role into how to stop the killer. They seemed more interested in throwing a lot of different "How'd that happen?" moments and didn't focus on incorporating them into the mystery. There was a shocking lack of even a single red herring and in the case of the Lion, Man, Eagle cross, we weren't even made aware of the riddle until Holmes was solving it.

Still, the banter between Holmes and Watson was great and it was mostly enjoyable (although I'd have gotten rid of most of the action scenes). Honestly, the film's biggest influence on me was to make me want to watch the superior and very similar Young Sherlock Holmes.
