60s were a time of shameless rip-offs that were nearly or sometimes as good as the original. I was always an Addams Family guy, and would happily remake that series if I were in Hollywood, as it's still better than any of the movies that followed... Munsters is good for other reasons, and the main one being how shamelessly blunt it is about exactly WHAT it is. Oh, and it was mostly good because of Fred Guinn, the star. He was absolutely fantastic. You cannot have The Munsters without him. It just doesn't work, IMO.
Other good 60s shameless rip-offs:
- The Outer Limits from The Twilight Zone
- I Dream of Jeanie from Bewitched
- The Monkeys from The Beatles: Help
