That's where my wife and I most frequently split. Even in the pre-streaming era, she would buy me DVDs of movies I said I liked, even though I would almost never rewatch them. The Indiana Jones movies, the Back to Future movies, the Star Wars movies, I'll watch those. Fargo is probably my favorite movie ever, and I can still only rewatch it so often.
Having kids has been great for rewatching with them for the first time. Star Wars is great, because for better or for worse there is so much content, and even the worst of it is extremely rewatchable. Indiana Jones is the tough one. We watched before 5 came out. 1 and 3 are both probably in my 3 favorite movies of all time, and 2 and 4 are awful. 5 was also bad. I'd be inclined to start to harry Potter movies, but my wife wants to read the books with them first, and they seemed to lose interest at some point
