Have you seen Sherlock Gnomes yet? Has anyone?

That's what I thought.
If you like cartoons and Sherlock Holmes, you're much better off watching Disney's 1986 classic The Great Mouse Detective. It's pretty wonderful, and it has (for my money) the best Disney villain in any film. This guy:
If it's been a while, here's a refresher: Basil of Baker Street is a mouse Sherlock who has to solve the mystery of a kidnapped inventor. On the way, he meets sexy saloon mice, a psychotic bat, and the mouse-queen of England. It's a blast.
I wrote a review on Film Table if you're interested.
