“Scoob” (***1/2 out of four) was a superior animated children’s film about Scooby-Doo (voice of Frank Welker) who discovers a plot to unleash the dog Cerberus (voice of Fred Tatasciore) upon the world and him and his gang (voice of Will Forte, McKenna Grace, and Amanda Seyfried) have to race against time to stop the dogpocalypse from happening. Lush and luminous animation designs are highlighted even more by a snappy screenplay that never stops moving and never stops entertaining. Particularly fun for kids but also for fans of the “Scooby Doo” series and animated movies in general.
