Yep, I got spoiled on that one too. I always try to avoid spoilers. I hate knowing what's going to happen and can't understand why people would want to know but, hey, that's up to them I guess.
But I was reading something online that had nothing to do with the Sixth Sense and some jerk in a talkback felt it necessary to make sure that everyone knew that he knew the ending of the movie. It was very important to him. Jerk.
Two guys in my office were having a conversation about "The Sixth Sense" which I hadn't yet seen and I had intentionally avoided all spoilers. I begged them to stop talking about it:
Me: "Guys, PLEASE don't talk about this movie, I haven't seen it yet and I don't want to know the twist."
Guy: "Yeah, but..."
Me (shouting): "Seriously! NO SPOILERS! I do NOT want to know what the twist is!"
Guy (grinning): "Yeah, but you totally would figure out that Bruce Willis is dead anyway."
Me: (devastated as a I REALLY REALLY did not want to know and it ruined the whole movie for me): "I will never forgive you for that."
And I haven't. And he was a writer. You would think if anyone had respect for story and audience...
