It seems like other raters including CommonSense Media didn't actually watch the movie! I only saw the last half, maybe less, and it was awful. It was scary and violent for young children, but to me that wasn't the worst part. Many girls were dressed in very skimpy clothes (extremely short shorts, lots of cleavage showing, etc.). After reading the CommonSense Media rating, I let my 8-year-old daughter watch the movie with her father because she likes Scooby-Doo. As only one other rater seemed to notice, there was a part where Fred and Daphne's bodies were switched. Fred, inside Daphne's body, said very happily/sexily: "Hey, I can look at myself naked!" while he (she) looked down and smiled at Daphne's breasts/cleavage. Then Daphne, in Fred's body, watched Fred (in her body) touch himself and said "get your hands off me!" but Fred was very disrespectful, wouldn't listen to her and kept touching her body (which he was in). Later she said "Fred keeps touching me!" There was also one subtle reference to drugs/being high that I noticed, when Fred's character says to Shaggy (in a paranoid voice like someone who is high and hallucinating), "Listen Man, someone must've spiked my root beer last night!" Then he assumes it's a bad trip and he's high and asks Shaggy to help him come down from his drug high he thinks he's on: "Talk me down, man, talk me down"!
