Query: Knock Knock..Whos There? WHO CARES

Knock Knock had all good intentions.a good story ,a great tag line.Too bad the characters were so unbelievable..Like the big breasted blonde bimbo for the police detective"Yea ok".The killings were done in fast motion so you couldn't really see what was going on most of the time although there were a couple of redeeming kill sceneslike the blow torch and the shower scene.The acting was off the charts bad..and it was very predictable..The mask the killer used was like a generic Leather face mask..I only bought this because I was in WalMart and needed a movie to watch and I saw a copy of this and cover and the pics in the back made it look good as did the synopsis.but NOT..
