I think there’s stuff you can be exposed to before you are old enough to really appreciate it. My parents used to watch period dramas that I was bored senseless with and now agree are fantastic.
It can also work the other way as in Simon’s example, in teen years you think you are too old for something and when you better understand the context was brilliant.
Saying that Mark’s list wasn’t restricted to narrative material. I used to hate all fruit being cooked, I still mostly do but I quite like a pineapple on my pizza. I also had a low tolerance of spicy food and used to order the mildest dish at Indian restaurants, then I got sent to work in India and had to eat super spicy Hyderabadi food. I went back to the UK and ordered a ‘hot’ dish and thought it was quite bland.
