Re: Most obvious plot "twists" (spoilers)
One of my crowning achievements in life so far has been guessing that Willis was dead about 15 minutes before the climax of The Sixth Sense. I wouldn't call it an obvious twist at all, but I sniffed it out.
MALCOLM: "Mr. Tickel is dead. What are you going to do about it?"
NICOLA: "Well, I'm not going to exploit a suicide."
MALCOLM: "Come on, you can't look a gift corpse in the mouth! You should be taking that corpse and slapping the government about the face with it."
