Never really understood why people are so concerned, one way or another, with spoilers. Perhaps I don't understand this because I am a voracious reader, and the vast bulk of films I'm interested in are based on books which I've been sufficiently interested in, that I've already read them.
If I wasn't interested enough in a story to read the book, why the hell would I be interested in a screen adaptation of said book?
I am pretty much accustomed to seeing films where I know most all the major plot points and twists, well in advance of going to the theatre.
Having foreknowledge of what's going to happen in a film has rarely, if ever, "spoiled" the film-going experience for me. (If that weren't the case, I'd likely never again see any movie that was based on a historical event.)
