According to IMDb's 4.4 rating, "Shaggy & Scooby-Doo, Get a Clue!" is the worst "Scooby-Doo" series out there. While it's certainly a departure from the traditional series format, it's not nearly as bad as you might think. Sure, the animation style is a bit strange, and the lack of Fred Jones, Velma Dinkley, and Daphne Blake is unfortunate, even if they do show up every once in a while. Nevertheless, there are some pretty fun additions to the "Scooby" story here. In "Shaggy & Scooby-Doo," Shaggy's wealthy Uncle Albert goes missing, leaving his fortune, robot butler, and the secret formula for Scooby Snacks to his nephew Shaggy Rogers, which sends Shaggy and Scoob on a strange adventure of their own. Before they know it, this dynamic duo find themselves on a mission to save the world from the evil mad scientist Dr. Phibes. 

In this iteration of "Scooby-Doo," each Scooby Snack gives Scooby a different, limited-time superpower, which could irk traditionalist fans of the franchise. But since Scooby and the gang have been around doing more or less the same thing for so long, it's nice to shake it up every once in a while. Plus, the series has a super-catchy theme song that'll easily get stuck in your head "all day long."
