The plot is basic with a villain on the loose that needs to be stopped. But there's nothing that makes it Scooby Doo. No plot twist, no unmasking the true villain, no secrets, and the entire time you just know what's coming and nothing surprises you. It does bring a call back to the original by having old villains, great sound affects and animation. But there lacking what makes Scooby Doo, Scooby Doo.
