Funny. I was watching an episode of The New Scooby Doo Mysteries with my three year old and was surprised (okay, not so much) that the last act seemed to have been stolen for reuse by George Lucas and David Koepp in Indiana Jones and the Kingdom of the Crystal Skull. In the Scooby episode a giant ruby was returned to it's resting spot allowing a spaceship to toot off into the unknown. Replace the ruby with a crystal skull... I also believe that the Mutt Jones character is based on Scrappy Doo. Finally, KotCS should have had more zombies. The Scooby episode had zombies which I found both terrifying and riveting.
