I loved this show as a kid and am thrilled that's it's finally available (via an all region disc set from Australia). There weren't really a lot of sci Fi tv shows between star trek and star wars, so anything hinting at sci-fi or fantasy was a hit with me. Of the American shows, TFJ had the wildest imagination and most action. But it is amazing how little money they spent on episodic tv back in the 70s (hilariously so at times). The set design in the episode An Act of Love utilizes more crinkled-up aluminum foil than I've ever seen in one place! 1000's of rolls of it I'd guess. And it looks like they hired an entire kindergarten to glue it to massive amounts of styrofoam and cardboard. That said, the story is pretty good, as most of the 10 stories were. The show runners aimed for high camp spectacle but often had to settle for kiddie school pageant sets and effects.
But most shows back then didn't even try (or tried too hard, like Space 1999). I love that this one gripped that plastic whiffleball bat it was given and swung for the cheap seats!
