There's a big old (theoretical) spoiler for The Sixth Sense, and a few other possibles.
That's what I thought, too. But, you know me. I don't think spoilers apply to a film that's been in release for such a long time. Especially one, the central twist of which has so firmly etched itself into the pop-culture subconscious of the times, as The Sixth Sense's one obviously has.
I know I fight a lonely battle, but I shall overcome.
