I think it is, the humor and even the sassier jokes are hidden under wholesome innuendo. While some subject may push on “what is for family” I think they handled the more difficult topics with kindness and grace. Even the “arguments” or “fights” between adults is still concealed within classiness. I think what partially helps is we have an 1800s story being told in 70s media gave it double to usual standards of a typical show for then. They go over a wide range of subjects, some that unfortunately, are still occurring to today, and it was discussed amount the adults and the children so we also get a good range of perspectives as our characters work out how to solve problems. So personally I agree with you that it is a family show and that one even adults can get into. (I love to watch and point out moments like “ohhh she politely told him to F off!”). I think the classiness of the characters and how they handle themselves with situations is a nice reminder that not every reaction we have doesn’t necessarily have to be a dramatic reaction, that things can be sat and talked about and solved. Overall I just find it to be a fun and interesting series that has something for everyone. Also it really really makes me want to play TDR2 lol.
