I liked the movie, it had a great message about friendship between man and dog as shown through scooby and shaggy, to blue falcon and dynomutt, to even dick dastardly and muttley. Even if this doesn't have a "traditional" scooby doo plot and has a simplistic message, It is a nice introduction to the hanna barbera cinematic universe, with tons of references to their classic cartoons that fans will enjoy. I wonder what they'll do next for the HBCU.
