Query: Probably the worst cartoon that has ever been created.

I've been an admirer of most of the Hanna-Barbera cartoons, but 'Scooby Doo' is one whose sucess seems a real mystery to me.The plot of every single episodes is just exactly the same. The gang is working on solving a mystery of a lost treasure supossedely taken away by a monster, ghost, or any other creepy character. In the end the find out that such creature doesn't exist and it's a person in disguise trying to steal the treasure. Frankly I don't understand what is so good about this crappy show.If you wanna see Hanna Barbera at their highest level of creativity, get 'The Flintstones' boxed set, because by watching one episode of Scooby Doo, you might as well have seen them all.
