Knock Knock - Der Tod lauert vor deiner Haustür

In Glass County, several teenagers from high-school are slaughtered and their severed bodies are found in the working place of their fathers. The retired detective Mike (Antonio Mastrantonio), who is the absent grandfather that is trying to approach to his granddaughter Nikki Reynolds (Joli Julianna), teams up with the inexperienced Detective Billie Vega (Kim Taggart) to help her in her investigation, where the slow janitor Troy (Sal Sirchia) is the prime suspect.

The lame "Knock Knock" is a terrible movie: the story and the screenplay are ridiculously bad; the unconvincing acting is awful; the camera work is dreadful. The only thing that works is the cover of the DVD that induced me to buy it. My vote is three.

Title (Brazil): Not Available

If there is one improvement I want from IMDb, it's the rating system. Instead of a 1 for the lowest, least-likable film, I think IMDb should have 0 as the lowest. Because there are just too many films nowadays that don't deserve even 1 star. This film is one good example.

The film is flimsy, the acting is fake and unbelievable, and it's definitely not something you would want to waste your free time watching.

The school kids got killed systematically by a wretched butcher who goes around knocking (mind you, the killer's pretty polite) and then stabs you to death. We've got so much to fear nowadays, what's with the global warming and all, and having a fear of checking out who knocks on your door just seems ridiculous.

Verdict : Avoid at all cost .

If I could rate this movie as a zero I would - but the lowest rating is a 1.

This movie looks as if some high school kids broke into their AV department, stole some equipment and decided to make a movie.

The DVD boxes these movies are getting displayed with are so much better. I used to look at DVD cases to see if it looked like a cheesy B-movie flick -

this one didn't look like a bad one - I was wrong- it was pretty bad.

If you are willing to waste an hour and a half of your life, do it watching paint dry instead of this.

I just love the name of the production company though - Aeriola productions!

I am a true movie buff and usually am one that really seems to love movies others hate. I could find something good in them but this one ... not so much. It had a decent story line and could've been a really good movie if they had written it a little different and OMG the acting was horrible! I kid you NOT overdone, ridiculous reactions and facial expressions let alone the lines. I wouldn't let them put this on my resume as an actor. Most of the time I would read a review like this and say, okay gotta watch to see if it's that bad, don't waste what precious little time you have left on this earth with this movie. Unless you like to laugh at bad acting. I was really disappointed. It was so bad you couldn't even make fun of it. I cannot stress enough how bad the acting was.

In Knock Knock, the sins of the fathers are visited on the children, as a disfigured maniac slaughters the kids of those accidentally responsible for his terrible injuries.

When a slasher features an excess of mean spirited gore and plenty of curvaceous beauties (including some topless nudity during the obligatory shower scene), I can usually make allowances for a derivative plot and dreadful performances, but so abysmal is the camera-work and editing, mostly during Knock Knock's all important death scenes, that I can find little forgiveness in my heart on this occasion. With horrible 'wobbly cam' and that annoying flickering effect that accompanies rapid cuts in so many contemporary horror films, I soon found my patience wearing thin.

It's a shame, because if writer/director Joseph Ariola had just kept it simple, rather than trying to be 'stylish', his film could have been a whole lot more enjoyable—a good old-fashioned, unpretentious stalk 'n' slash that doesn't wimp out on the splatter (victims are repeatedly stabbed, burnt, eviscerated and dismembered). As it stands, there's a good chance that the erratic execution of the film's kills will induce a seizure, which isn't really what we want, is it?
