Rereading a book, one could pick up on things that were missed previously or that have been forgotten about. Also, one might be in a different life situation or mindset from one read to the next which could alter the perception or enjoyment of what's being read. Not to mention that some prose can be appreciated for its beauty.

TV shows, movies, and albums are often revisited by people who enjoy them. Even as I write this, I'm listening to an album right now that I've heard dozens of times before. I may not always be in the mood to listen to it, but my enjoyment of the music has not been eroded by how many times I've already heard it. Rather, being familiar with it, I appreciate both how it's composed, played, and the nuances that are now apparent to me that I certainly missed on my first listens.

One of my favorite books when I was younger was "Understanding Comics: The Invisible Art" by Scott McCloud. It was visually appealing to me at the time, but after several readings, I started to really grasp its concepts as an educational art book.

I also find re-reading books frequently have diminishing returns, but after some time, you and your world changes, which results in you having a different point of view when you re-read the book.

As you change, the meaning of the book to you changes as well, and gives you new perspectives along with new ideas. E.g. a specific villain or a side character in the book might not be attractive or simply confusing to you, but as you re-read the book, you realize that you get them and they now make perfect sense.

Books, TV series, movies, music...if I make some emotional connection while experiencing it, I'm likely to want to repeat that experience later.

When I buy a book (or in the olden days, a DVD/etc), I'm factoring rereadings into the value proposition. If I don't think I'm going to want to reread, I'll prefer to get it from the library.

So, most content in my personal library is there because I expect to experience it repeatedly. And I'll tell you, it can be fascinating to take some experience you treasured as as preteen, and then experience it anew from the perspective of a parent. It's pretty funny relating more to the dopey dad and less to the hero.

But not everything is about getting a different take on repeat experiences. Sometimes I just want another hit of whatever that piece of media made me feel.

I do both. And movies. If it’s not worth reading or watching a second or third time, it wasn’t worth it the first time. I read Hamlet every year or two. It gets me every time. I’ve seen the Maltese Falcon about five times, and it still amazes me with its perfection each time. I’ve seen the Pickle Rick episode of Rick and Morty three times, and I fully intend to watch it three more times. Pure genius. Anything good has layers and details that usually can not be fully appreciated the first time through. Do you only listen to a song you like once?

"Incidentally, I use the word reader very loosely. Curiously enough, one cannot read a book: one can only reread it. A good reader, a major reader, an active and creative reader is a rereader. And I shall tell you why. When we read a book for the first time the very process of laboriously moving our eyes from left to right, line after line, page after page, this complicated physical work upon the book, the very process of learning in terms of space and time what the book is about, this stands between us and artistic appreciation. When we look at a painting we do not have to move our eyes in a special way even if, as in a book, the picture contains elements of depth and development. The element of time does not really enter in a first contact with a painting. In reading a book, we must have time to acquaint ourselves with it. We have no physical organ (as we have the eye in regard to a painting) that takes in the whole picture and then can enjoy its details. But at a second, or third, or fourth reading we do, in a sense, behave towards a book as we do towards a painting. However, let us not confuse the physical eye, that monstrous masterpiece of evolution, with the mind, an even more monstrous achievement. A book, no matter what it is—a work of fiction or a work of science (the boundary line between the two is not as clear as is generally believed)—a book of fiction appeals first of all to the mind. The mind, the brain, the top of the tingling spine, is, or should be, the only instrument used upon a book."

--Vladimir Nabokov

It depends heavily on the genre, at least for me. So-called genre fiction--mysteries, sci-fi, fantasy, that sort of thing--really doesn't hold up to rereading, since the whole draw is, by and large, the setting and the plot. I still remember the solution at the end of Murder on the Orient Express, and I still know how Liu Cixin's theory of galactic civilizations is going to play out in the Three Body Problem, so there's not really a draw to reread those books: the language is serviceable but not exciting (at least in the translated TBP), there's no real symbolism/inter-textuality to dig into on further readings, &c. However, I still find myself rereading favorites like Gravity's Rainbow and Moby Dick every few years: the jokes are still funny, the language is still beautiful, and it's still enjoyable to ponder the references and metaphors the authors are (possibly) building.

Your comparison to television is a pretty good one, honestly. I've never really rewatched an episode of a serial television series (other than trying to refresh my memory when picking up a new season), since there usually isn't any substance there beyond the plot and characters, but I'll happily rewatch movies if the directing, cinematography, and/or acting are compelling enough.

The complexity of A Song of Ice and Fire... You get a lot out of a second read-through. There the density of the plot development is so thick that you don't even know what you're supposed to focus on. Some things that are mentioned in the first few hundred pages can resonate much stronger after reading the last few hundred pages.

That's just one example. It obviously depends on the book. Getting "absolutely nothing" out of something seems more like a choice.

At different points in your life great stories can impact you in different ways. A simple example of one that could do this is The Road by Cormack McCarthy. I never had kids, but from what I've heard people who read it after becoming a parent are hit with far stronger emotions than those who don't have kids.

Actually, yes. I haven't done it with books, but there are a few shows I've rewatched. Usually it's something I enjoy having on in the background while I do other things, similar to having background music. It started as me just knowing I liked the show, and not needing to pay full attention to it to follow along. But I notice a lot of new things on subsequent viewing, and knowing the basic plot already I'm able to appreciate how the writers are setting things up, establishing the characters, etc. in ways that become very significant later. And the first-time through I just don't notice that kind of thing or appreciate it. It feels like getting more depth in the art of it rather than just experiencing more breadth from another artist.

> Do you also rewatch TV series

Good ones, with a lot of depth, absolutely.

I also look at paintings more than once in my life, consume my favorite meals more than once and so on. For those without a perfect memory, re-reading a good book can often teach us new things.

Rereading (or "reexperiencing") something can be very valuable. Since you already know where the destination is going to be, you get to focus your attention on more of the little details you might not have picked up on the first time through.

With that said, I only occasionally do it for books because of the time commitment. I have a large list of books I want to read, and only read about 25 books a year. So if I am going to reread something, it's usually for a specific reason or I am was in a specific mood.

While I understand the idea of rereading a few books here and there, it's pretentious assholery to imagine you shouldn't read new books because you're getting older. That's just an idiot who pretends to be the smartest guy in the room. There aren't too many types of people more pathetic than someone who never tries new entertainment. "I only like the old stuff". Because someone is only a good artist or writer after they've been dead for a century.

I think this really varies from person to person.

I re-read maybe 5% of books, and I tend to get a lot out of re-reading. Nassim Taleb said something like "if it's not worth re-reading, it was not worth reading in the first place".

My re-watch rate on movies and TV series is much higher, probably 85% of movies I will watch more than once. TV series, maybe 50%.

Some people just read or watch and never care to think much about it after. That's cool too; doesn't hurt me any.

The value of re-reading will be low if you’re reading high noise to signal books that could be compressed into a blog post (e.g. anything by Adam Grant).

If you read more dense books of philosophy, literature, or otherwise you’ll get a lot more value out of re-reading since you likely have missed things upon first read. Same thing with tv shows that contain a complicated plot vs. ones that are churned out for quick consumption.

I’m as surprised at your surprise! I’ve seen The Office in its entirety more than 10 times, my other favorite shows 3-5 times each, and most generally popular shows at least twice. Often when a new season arrives, I start again at season 1 if it’s been a while. Same goes for my favorite novels, of which there aren’t as many.

Perhaps it’s relevant that I have a terrible memory for plot.

I'm the same for fiction; I can't read a fiction book twice. My SO can re-read the same fiction over and over. I just don't get it. Now, there are some movies I can watch again. But only once or twice and then I'm done for a very long time.

Re-reading Pop-Psy and Airport literature is not the recommended reading. How about reading Hayek, Strauss for second time? How about reading man's search for meaning for the third time?

You re-read great works, not NYT best shiller! (sic).

I always find something I missed the first time around. Or I feel differently about the story. There's always something different.
