i really hope there is a Saw 4.! Yes, after a while they could get boring, but I've enjoyed the first 3 so far, so there's a really good chance 4, and even 5 if they go there, would be fairly good, if not great.
i dont know how they could make another one when everyone is dead, but no actually ISNT dead. the little girl. the one guy. sure, they have no food or water or a way out.
But what the Benj guy or whoever wrote, it seems too oddly specific to be made up.
I just hope theres another one, im in love with these movies =] ♥
