I got on this weird kick of looking up and watching old cartoons from the late seventies and early eighties that I remembered. most of these didn't last too long.
Hanna Barbera's short lived Space Stars revived Space Ghost and the Herculoids in an anthology format with two new features: Teen Force and Astro & the Space Mutts. the Jetson's dog was now having adventures with other talking dogs and the Burt Reynolds like Space Ace. the last episode of each show, the Space Stars Finale, featured crossovers between various characters.
The Super 7. all I really remember about this is Super Stretch. later, Tarzan was added to this anthology show. he was bumped out of the top spot the next season by Batman, of all people.
