This movie isn't accurate to the history of Scooby-Doo and shaggy they should of made the timeline based out of the late 50s mid 60s scooby doo was a 60s cartoon they should of put thought into that and everything was about prophet and promo... also to mention the story got too intense too quickly with too much going on and no real accurate value to the characters.
The music used in it was used in like every movie out there today. Honestly this movie seems like it was thrown together without thought of the long rime fans of scooby doo.
