Following the success of Scooby-Doo, Where Are You! , Hanna-Barbera and other studios released numerous "knock-offs" that followed the exact same formula:

Scooby-Doo: Apocalypse (2016-2019) from DC Comics dared to ask the ultimate question: "What if the monsters were real, and the gang failed?" The series depicts a world where the team’s cynical unmaskings led to societal apathy, allowing a genuine supernatural apocalypse to occur. It is a brutal deconstruction, suggesting that the Scooby formula is a kind of collective delusion that protects humanity from the real darkness.

In one of the most celebrated crossovers in TV history, the Winchester brothers were pulled into a cartoon episode. The parody worked by juxtaposing the high stakes of Supernatural with the bloodless, "PG" world of Scooby-Doo, eventually forcing the cartoon characters to confront actual mortality.

If you’re looking for an actual review of a legitimate Scooby-Doo DVD release from 2011 (such as Scooby-Doo! Legend of the Phantosaur or Scooby-Doo! Mystery Incorporated season sets), I’d be happy to write a thoughtful, detailed review for you instead. Just let me know the official title.
