Excellent but underrated film

This story has more twists and turns than a second-rate soap opera.

It really made me laugh, but for some moments I was tearing up because I could relate so much.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

Everywhere I seen a review of this movie it was always the same, this is bad. So I was ready to view it, only one problem, not available over here but fortunately a good friend offered me a full uncut version. Only 1 minute into the movie I already knew something was terrible wrong. The first girl murdered was dressed sexy. Not that I have a problem with that but mostly that attracts more then the gore. Anyway, the good part of the movie is indeed the gore. It's not all in front of the camera but they really show the result. It's gory but easy to take. But there is of course the movie itself. The acting of some is really bad. For example the interrogation is a big laugh, she never impresses me as a copper. And the killer is a cheap version of Leatherface, his clothes, mask and hair is a copy! Furtheron they also listened what they did with Evil Dead and Nightmare on Elm Street, I mean the children singing chants. Some scene's are too long, could have edited it better. And some scene's had nothing to do with the movie, for example when one of the guys goes home with his girlfriend her sister opens the door, what we have next is nice to see but has nothing to do with the script, and a lot of girls show their body, clothed, in an explicit way. I told before, I have no problem with that if that doesn't let you forget the storyline. I gave it a 3 just for the gore, could have been much better...

Certainly a horrible movie..Its the worst movie i've seen.Really Bad..If I had an option to vote as zero I would choose it..In the movie there is no horror, no action, shortly nothing..I watched this movie with my friend's advise.Because, he has been watched the movie and he was repentant and he wanted me to be as well as him..So an advise to you, if you don't want to be repentant do not watch.Thus save your time..

I didn't even bother watching the end. It was pointless. This was a stereotypical teen slasher movie without anything new to add to the genre. In an effort to make up for a poor story and poor acting, the producers and directors give us a full serving of hot young bodies to stare at so that (they must hope) completely miss the fact that the movie is horrible. If all you are looking for is eye candy (and there is plenty of that) and lots of blood then this is probably the movie for you. Of course, you probably enjoyed zombie strippers as well. If you're looking for a GOOD horror movie that is suspenseful and scary, you've come to the wrong place.

Bloody, gory and well photographed slasher flick. Acting is atrocious, but cast features a score of knockout beauties. There will be a few empty chairs at graduation. Kim Taggart plays detective Vega, who is lead detective on a very puzzling case. A serial killer causes citizens of a small town fearful of opening their front doors...that is where he nails some of his victims. A group of popular high school students encounter a deranged killer that teaches them a few lessons. The number one person under suspicion is a traumatized loner at the school. The body count increases rapidly. Some pretty disturbing images may just be the only redeemable thing about KNOCK, KNOCK. Also featured are: Suzi Lorraine, Antonio Mastrantonio, Nicole Abisinio, Joli Julianna, Kat Castaneda, Anthony Palladino and Chris Bashinelli.
