We watched M. Night Shyamalan's The Village tonight. Its pretty good, better than Signs, but not as good as Unbreakable. Not sure about the Sixth Sense, though I should point out I figured out the ending within about 5 minutes (and then once the dramatic confrontation occurs, figured that out pretty quickly too). My wife didn't, though in fairness, she blurted out the Sixth Sense's twist within about 5 minutes of it starting.
In any case, its certainly worth a look.
