* Despite their niece, Marilyn's, "deformity" (as a normal human, she's considered "hideous" by the standards of the Munsters), it's obvious that Herman and Lily (and the rest of the family) genuinely love and care about Marilyn--Herman and Lily obviously see her more as their daughter instead of their niece, and they and the rest have even done stuff like try to help Marilyn find a boyfriend (always with poor results, but it's the thought that counts).

* Far Out Munsters has the family interacting with a group of young hippies renting the mansion for a weekend, and generally having a great time with them. While the episode has an element of making fun of the weirdness of the Hippy movement, it's indeed charming to see a group of people not being judgmental of the Munsters' appareance.
