The absolute worst is the remake of what was a classic children's movie, "Willy Wonka and the Chocolate Factory" with that creepy Johnny Depp in the Gene Wilder title role.
It's not a remake because both films are based off of a Roald Dahl book. The Depp/Burton version is much more closer to the original work, which like much of Roald Dahl's books, is pretty creepy.
