Knock, knock? Never heard of it. What's that about? Darien, trust me on this one-don't even waste your time my friend. It is a movie that my local Blockbuster had I got one day when there really was not much else to rent. Truth be told, I would have been better off not renting it to begin with.......LOL!!!!! :rolleyes::rolleyes: It is really that bad. :o:o Cheers, Phil
