Jeff is the dumbest horror character I have ever seen
He goes back in the house several times knowing there is a killer loose and has no reason to go inside. He makes no attempt in finding a way off the property even though it took Seth 1 minute to get through the fence. And he has a fascination about going after the killer in the most dangerous places with a weak weapon while dragging his girlfriend along.
