Credit where credit is due: Fred Gwynne, Yvonne De Carlo and Al Lewis are what keep you coming back to the Munsters. Yes, the look of the show (Universal Horror all the way) is great, the writing often clever, the numerous sight gags usually entertaining. But if you didn't have good (very good) acting from the leads this show would have tanked.
Boiled down, the Munsters is a typical family sitcom in a bizarre setting. And while most of the episodes are fun, if feather-light, it didn't take long until the first clunker (#14: Grandpa Leaves Home). And that wasn't the last one but, thankfully, it's in the minority. The reason, again, is that Herman, Lily and Grandpa (along with the kids and numerous guest star appearances) are, frankly, endearing. You become so fond of them that some episodes actually become touching (Happy 100th Anniversary).
Only 70 episodes but that was about the limit of what you could crank out without it becoming painful. Too many sitcoms run on past their welcome. This one managed not to.
