The whole famous as they are are pretty awesome: Dracula, Dracula's daughter married to Frankenstein's creation, a kid werewolf, their pet dragon, pet bat, wisecracking raven, the cat that roars, and the Muggle that loves them all.
Herman's famous speech to Eddie about how your race and appearance doesn't matter; it's what's inside that defines your character. It's the early 1960s, in the midst of the Civil Rights movement.
The lesson I want you to learn is that it doesnt matter what you look like. You could be tall or short, or fat or thin, or ugly- or handsome, like your father- or you can be black or yellow or white, it doesnt matter. But what does matter is the size of your heart and the strength of your character.
Grandpa's experiments are all awesome as kooky as they are.
Herman and Grandpa winning the drag race in the Dragula. For that matter, the Dragula and the family car, the Munster Koach, are both awesome vehicles.
Eddie winning the race without Grandpa's magic pills. How did he do it? He cared that much about not making Herman, his coach, feel bad. Doubles as Heartwarming.
In a way, how quick Lily is to go out and find work in a time where it was still expected of women to be housewives. She takes on a number of jobs, ranging from normal ones like secretary to nurse's aid, to more unusual ones like modeling or welding. She's clearly driven to support her family and has a range of talents. This was kind of progressive for the early 1960s.
Lily was rather liberated for a 60s housewife. Besides working, she was independent, assertive, and never afraid to stand up to Herman, even during his fits. In fact, he was the one wrapped around her finger!
Both the season 1 and 2 theme songs are pretty awesome, but notably s2's surf rock version.
Lily beating Herman in arm-wrestling.
The 2022 Film
Herman's punk rock band was pretty awesome.
The ending, where it turns out Lester got the money back and repaid all he owed his family, who are overjoyed to finally have a stroke of good luck.
Wolfgang's experiment being a success (albeit not at all in the way he wanted).
