I gave up on Scooby and gang a while back. Their movies have just gotten too flimsy in the plot dept, and come to think of it, so has their last few series incarnations. Incidentally, wasn't there a movie with nearly the same plot Called the Phantom of the Amusement Park? That starred Kiss too, and involved robot doubles or something.
