The “who is this for” is the question that kept running through my mind. They wanted to cast as large a net as possible and in the process caught no one.

From what I understand the show runner had her own original property she was pitching and the tv execs wouldn't green light it because it was too risky, so she convinced them to let her run a Scooby Doo origin story, and then Rewrote it with her unsold show as the concept.

So she basically launched her own ip using Scooby Doo as the vehicle to sell it.
