I really liked this movie I am a big fan of Scooby-Doo and I really enjoyed this movie. The whole cast was great. I especially liked Linda Cardellini's Velma. It really sounded like Nicole Jaffe's original voice. I have to disagree with Jerry, this isn't a kid's movie. People of all ages would enjoy this. I especially liked the part where Scooby was dressed up as an old lady, posing as Shaggy's grandmother, then he started chasing that cat. That was hilarious. I also liked when Daphne (Sarah Michelle Gellar) was talking to that guy who told her not to go near that castle. "You want me to go to the castle, that's why you told me not to go to the castle, unless you knew that I'd figure that out, so I wouldn't go to that castle." I liked that dialog. As for Scrappy-Doo, I agree that J.P. Manoux did a good job with the voice, but why did they make him a bad guy? I remember he saved Shagg and Scoob from being eaten by a monster on the "Reluctant Werewolf." I understand that a lot of people dislike the character, but I thought that making him evil was a bit strange. And about Scooby, it might not have been Scott Innes who did the voice. I read in a news article that it was some guy named Neil Famming, but whoever it was, he was really good. Overall, this was a good movie. I'd be interested in seeing it again sometime.
