The best thing The Mothers-in-Law has going for it are the comic stylings of Eve Arden and Kaye Ballard. The actresses have great timing, good chemistry and liven up an otherwise dull show.
For me, the main problem of The Mothers-in-Law is that even for the late 60s, the show seems dated and stale. As the show goes on, you start to feel as if every episode is a variation of: "Kaye and Eve are told not to engage in a certain activity. They then proceed to engage in that activity. Wacky hi-jinks ensue." It's essentially a retread of I Love Lucy, which makes sense, given this show involved a lot of the same writing staff as Lucy. However, what seemed fresh and clever in the early 1950s is less appealing nearly twenty years later.
I would say you should watch this show mostly as a curiosity. It's entertaining, but nothing all that memorable.
