this is the first Space Ghost cartoon aired. I've seen it so many times now it's not funny. I hadn't seen Space Ghost in years, and then I was in a store and saw a VHS tape with three episodes (and one Dino-Boy) on it. I bought that one right away and watched it a lot. I didn't realize there had been a series of tapes from the H-B archives already, usually in hour format. I later found the Shazzan and Mightor/Moby Dick ones to rent.
this is a good episode. no reason is giving for the Heat Thing to exist, and in seven minutes it isn't needed. you get a good look at all of Space Ghosts powers and Blip isn't that annoying here (i.e. he doesn't save the day).
