Scooby-Doo Meets the Boo Brothers/YMMV

Non Sequitur Scene: The movie opens with one of these. A ghost (or witch) scares Scooby, Shaggy and Scrappy into the car, while singing about no matter how scary she is, the Boo Brothers are scarier.
Rescued from the Scrappy Heap: Scrappy is a bit more bearable in this movie, since he's needed to solve the riddles until Shaggy gets enough of a clear head to figure out the last few. Also in the opening when he heard about ghosts, his first thought isn't to fight them, but that ghosts are neat. The two people he seriously confronts in the movie are the butler and the gorilla, neither of whom was a person in a costume anyway.
- He also saves Shaggy and Scooby by tricking Billy Bob into getting chased away by a bear.
- And he's the first to think that maybe the escaped ape isn't viscous, but lost and scared. He's right.
- Still, it gets annoying at times the way he solves all the clues.
Values Dissonance: The main ghost is shown wearing a Confederate uniform, and Shaggy is explicitly stated to have inherited a Southern plantation, and this was at a time when the belief the Confederacy fought a noble cause and that the civil war was caused by both sides was still widespread. Nowadays, with a greater awareness of exactly what the Confederacy fought for, the preservation of the slave trade, it would be absolutely impossible for either event to occur without the serious implications of it being brought up in the film, especially for a kid's film.
