> I think this is an act of a generosity. It shows that an artist is not only competent enough to execute something that complex, but also thinking deeply of their audience's time and money.

If the artist is thinking deeply of her audience's time then she should not make the book (or art) worth rereading. Putting things at the beginning that only make sense at the second reading is rude and inconsiderate to the audience.

Well, this is my view of the books or shows that have rewatchability anyway. Fuck them, I won't. Also screw the artist for messing with my time.
