I have decided to rank the Hanna-Barbera crossovers by favorite to least:
1. The Jetsons & WWE: Robo-Wrestlemania
2. Scooby-Doo & WWE: Curse of the Speed Demon
3. Scooby-Doo & WWE: Wrestlemania Mystery
4. The Flintstones & WWE: Stone Age Smackdown
This movie is my least favorite of the four because it feels forced. It is a huge lesson about betraying your friends and playing fair. I wonder that, unlike the other three movies, its target audience was a younger demographic.
