On re-reading books:

The first time I read Infinite Jest by David Foster Wallace I found myself unable to determine what was Important for much of the first few hundred pages. None of it made sense and I couldn't figure out what The Point of the book was. I kind of read the pages but didn't really take any of it in.

The second time I read it was a completely different experience: those first pages immediately made sense, and I derived a sense of pleasure in reading them that I didn't have the first time around.
