Because my rating is solely for the first season, which was already a mixed bag.
The 2-4th seasons are in entirely other format, and not even mysterie-solving. Actualy, the "stories" degenerate to Shaggy, Scooby and Scrappy burglaring to someone's place (usualy a supernatural being, just to elevate the experience from rock bottom to center of the Earf), insult the owners, cause massive property damage, then escape, while the audience is supposed to cheer for them.
Now this part is bad. Let's say 3/10.
