I've read only small portions of the script, but I basicly know how it's going to end because I've seen so many spoilers while reading interviews and conversations on various sites. The pictures pretty much give away who will stay alive at the end, and which ones die. I dont feel bad about reading those stories, but I wish I never looked at those pictures, released/leaked yesterday.
One promise I made to myself that I'm intending to keep, is that I will not check out the boards when the movie is released. Just to avoid other spoilers of other unforeseen events.
