If you fall in love with a book or movie, do you tend to watch/read it again and again? If so, what's your upper limit on repeats?
About 3. The second time is for noticing and appreciating all the little details that you missed the first time around because you were so intent on finding out what was going on and getting to the end. And the third time is just for fun. Any more than that and I have to leave it and not watch/read it for at least a year, so I've forgotten the details.
