I feel bad for the people who spent years working on this show whose work will now likely never be seen, but at the same time I don't feel too bad about losing this one. Not because it is/was a preschool show, if a popular IP can appeal to kiddos, that's fine; but the casting here left a bad taste in my mouth; namely, only using Scooby and Shaggy as counselors and once again shafting Fred, Daphne and Velma, then having three OCs who are essentially those same characters as puppies. What is this, the 80's, where we still putting 3/5 of Mystery, Inc. on the shelf? I thought by now we all realized that the Scooby Gang works best as a Five-Man Band. If the producers really wanted puppy characters for this show, why didn't they just use Scrappy-Doo? It's been long enough; I'm sure most of the vitriol for Scrappy has died down by now.
Here's how I would've cast this show: I'd have had all five members of Mystery, Inc. working as counselors, and for the campers I would've cast Scrappy and his two best friends from the episode "The Ransom of Scooby Chief", Duke and Annie. There's your Mystery Pups right there.
