#10 - Sherlock Holmes 2
Normally, the problem with sequals is that their story fails to live up to the story of the original. Luckily for Sherlock Holmes, living up to the original story shouldn't be a problem. The two problems with the first Sherlock were the slightly boring story and the honestly unthreatening boring villain. With Proffesor Moriarty coming into play the villain part is already solved, so all they need to do to make this a perfect sequel is a good story that will give the characters a bit more to do than be witty at each other. (Though in the last film, the characters alone were enough for me to leave the theater impressed.)
