I remember first seeing this series (dubbed in Spanish) on Venezuelan television (and in black and white!) when I was growing up. Very fast paced show, but at only half an hour per episode, very little was done to really flesh out the cast of characters or the Protectors Organization.
The theme song is a personal favorite of mine. Surprisingly, it became a hit on Britain's music charts, some thirty years after the show's run ended.
Kudos to A&E for bringing this classic - some may call it a cult - TV show from the archives. While it appears somewhat dated (1970s), the writing of the series was superb.
