Lemony Snicket's A Series of Unfortunate Events (2004)
Synopsis
After their parents perish from a fire that destroyed their entire home, the three Baudelaire children - Violet, Klaus, and Sunny - are put in the guardianship of a mysterious actor named Count Olaf. The children soon learn that Count Olaf wants them dead so he can have their large fortune. Eventually, the children are taken away from Count Olaf, but Olaf follows them and disguises themselves, infiltrating and jeopardizing their next two guardians.
Review
Reasonably true to the books, but I think the large mistake that maybe didn't work was trying to combine three books into the same movie. The movie actually covers three of the Series of Unfortunate books: The Bad Beginning, The Reptile Room, and The Wide Window.
