Audio/Video. Both are quite good. The video is presented in 1.33:1 full frame, and looks really nice. It looks old, but I would be willing to bet it has not looked this good since it's initial release over forty years ago. The audio is a perfectly serviceable mono track. It is fantastic to see studios treat these older shows with the respect they deserve.
Extras. There is a single extra on this two-disk set, the feature length (96 minutes) documentary on creator Alex Toth: Simplicity: The Life and Art of Alex Toth. The creator is described as an artist's artist, someone looking to do the most with as few lines as possible. He is also described as a great friend and collaborator, as well as one of the most difficult guys they've ever had to deal with. It features interviews with contemporaries, those he influenced, as well as his children.
Bottomline. This is a great slice of old school toons, featuring an iconic character (with that great signature voice provided by Gary Owens) and plenty of action. Sure, Dino Boy isn't as good, but watching each episode is a blast. This is an easy recommendation for Space Ghost fans, or those who like the classic Saturday morning cartoons. With all the sets that are coming out, you could probably program yourself a Saturday morning that nearly replicates the days of old. Also, I am sure most of you are aware of Space Ghost's career change, in the late 1990's Space Ghost returned to television as a talk show host, quite funny, but a radical departure from the superhero roots of the character.
