I fully agree with your point; and I have also been to Dōgo Onsen. I would go a step further and say this: even if a piece of entertainment (or history) is based specifically on "something," and you enjoyed that entertainment, it doesn't guarantee that you'll enjoy that "something."

However, people can have fun however they'd like. If you think it sounds awesom to drink a coffee in the same shop Edgar Allan Poe drank a coffee a hundred years ago, that's cool!
