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?
No. No matter how much I love a book, my reading list excludes repeats (it shouldn't, but the thing is that I want to be able to just add up my annual tallies and say "this is how many books I've read since 2001" without having to subtract X amount for duplicate titles first), and so if I ever do then my brain is flashing WASTE OF TIME, WASTE OF TIME!! Either I haven't hit 100 yet, or I should be aiming to break my impossible record of 152. It's horrible but I can't shut it up. For books, I compromise by just flipping through them to read the good bits. Unless they are Harry Potter. Well, Harry Potter and something other than Deathly Hallows, which has yet to come 'round for a second read.
Movies I'm a little looser on, because while repeats don't count on the movie list either, I can multi-task when they're on, and it's not like I'm ever going to reach my goal of seeing 50 whole movies in a 12-month span anyway so I can't possibly knock myself off course. Of course, I've got so little patience for movies to begin with that you won't often find me voluntarily playing one. Exceptions to this rule include Home Alone (for Christmas), Never Been Kissed, Finding Neverland, PotC (mostly just #1), Enchanted, the first Harry Potter and A Knight's Tale -- and now that I think about it, possibly a few more -- all of which I have seen just a gosh darn lot of times and always consider a couple of hours well spent.
TV, now, TV's where the real repeating is at, which is partly why I have never objected to reruns. TV consumption is measured in responsorial commentary rather than raw numbers, which practically demands that any good episode is seen twice, and I can write as much or as a little as I want and write about it twice if I feel like it. I've made it its own kind of chain, hence why I am 22852 years behind on The Office, but for the most part I can watch good hours of TV an infinite number of times. Especially if they're, you know, sitcoms in syndication. Those never expire and they never get old unless they were atrocious to begin with.
