Huh? Jeff fufills the role of wise survivor. He's the exposition dump character. He explains the rules twice. Once at the first act climax when he abducts Jay and then again after the kids find him during the second act.Quoting Dukefrukem (view post)
This is part of what I was talking about--- the film, and by extension, its characters-- is so uninterested in its own mythology that it explains the rules twice. The second time, it adds information that the characters would have no way of knowing (that, if Jay dies, the creature will re-seek out Jeff and work its way "back up the chain"). Everybody is so braindead that nobody asks the point blank, obvious questions: What is this thing, where did it come from, how do we stop it?
They make guesses based on no information and arbitrary circumstance.
