Scoob! (alternate version)

We're not saying Scoob! is bad per se, but we tried to imagine how it would be if it wasn't a Hanna-Barbera crossover and more of a movie using the traditional Scooby-Doo formula.

Synopsis
After solving their latest mystery, Mystery, Inc. learns that several monsters they stopped in the past came into life and are led by a mysterious figure who wants to terrorize all of Crystal Cove's citizens as the gang heads to figure out the reasons that led him to unleash those monsters and stop him before Crystal Cove gets destroyed.

Changes

 * Although the celebrity cast is kept, Shaggy is kept with Matthew Lillard's voice since he is a celebrity voice as well.
 * However, Daphne is recasted with Karen Gillan and Velma with Jenny Slate.
 * The movie has a different plot in order to follow the traditional Scooby-Doo formula by having a down-to earth-plot and characters directly connected to the Scooby-Doo mythos instead.
 * The choices of Jason Isaacs as Dick Dastardly as well as Mark Wahlberg and Ken Jeong as the Blue Falcon and Dynomutt are kept for future installments set in a Hanna-Barbera shared cinematic universe and not in the movie.
