There is a fun podcast called Drunk History of Middle Earth that is essentially this dynamic the whole time - a husband/wife duo where the guy is trying to teach her about Tolkien. She's genuinely open to it, so it's probably less annoying than some other instances of that pattern. Aside from the hearing new perspectives on the lore, it's interesting to vicariously experience the stories for the first time again.

Also I love their accents, and how they sometimes expose their personal lives to the world and talk through stuff as a couple - it's very endearing

Edit to add: there are no ads! It's so refreshing
