Mediocre At Best . If you're expecting the same power and intensity of "Scooby Doo On Zombie Island" or "Scooby Doo and the Witch's Ghost," then you are setting yourself up for a disappointment. It is possible that certain powers felt that the first 2 Scooby movies were too much for children, but with this 3rd movie come a loss of impact, suspense, character development, and even mystery. It may be true that even a medocre Scooby movie is better than no Scooby movie at all, but this movie is almost boring after "Zombie Island" or "Witch's Ghost." Well, Scooby and the gang have car trouble in a desert. Fred, Daphne, and Velmah go on foot for help while Scooby and Shaggy spot what may be an alien invasion. With their famous and hilarious cowardly ways, they run and eventually meet the rest of the gang at a restaurant. At the restaurant, the gang is surprised that the other patrons don't seem so surprised about the presence of aliens. We also meet Lester who appears eccentric but still aware of what has been going on in the area. Lester lets the gang stay the night, and Scooby and Shaggy have their first encounter with the possible 'aliens.' Moving on, Scooby and Shaggy meet Amber and Crystal, and are attracted to them. They later meet the mechanic Buck as well as a team of scientists (that we already have met). Unlike "Zombie Island" and "Witch's Ghost," the misleads are not really well drawn. Also, rather than being surprised by the discovery of the villains, we are likely to be somewhat disappointed that it was so obvious. Even when we are presented with the most unusual character in this story (in this case it seems pointless to try to hide anything) it's nothing most people couldn't have figured out. I won't deny that there are some good moments in this movie. (For undoubtedly the first time, Scooby and Shaggy go to a restaurant and want nothing!) But even the old episodes were usually better than this movie. Parents may not have to screen this movie, but it is likely that even children will fall asleep during this one. Thank goodness for the eventual "Legend of the Vampire" and "Aloha Scooby Doo."
