There is a study out there that argues that knowing Spoilers can actually increase your enjoyment of a novel. SpoilerAlert: Stories are not Spoiled by ‘Spoilers’.
My first response to this was Get Out of Town, cuz I HATE spoilers. People who read the ending first baffle me. I refuse to even read series books out of order. In fact, I don’t read blurbs if I can avoid it. Too often I’ve seen them ruin a surprise in the first few chapters of a book, or raise false expectations or be just plain wrong. If I love a series or trust an author, I deliberately don’t read the back cover blurb. I prefer to have the story unfold the way the author intended. (Don’t get me wrong: blurbs are necessary. I would never consider buying a book by a new author without reading the blurb. Movie or book ads that rely on rave reviews drive me crazy. I don’t care if Such-and-such gave it five stars. I care about genre and PLOT.)
Different readers consider different things to be spoilers. My husband doesn’t understand how I can enjoy romance books when I know going in that the couple is guaranteed a Happily Ever After. (This makes me roll my eyes since the books he enjoys, SF and fantasy, have happy endings 95% of the time, too. The plucky hobbits defeat the all-powerful Sauron, not the other way around.) To him the HEA is a spoiler in and of itself. To me it’s a promise that I will be entertained and not depressed.
Here’s another article which argues with the original study’s conclusions: Scientific Explanations of Why Spoilers are So Horrible.
Do you hate spoilers? Do you ever reread your favorite books?
