knock knock be a new low budget horror film and which be unfortunately a really bad attempt at a slasher flick . i could not believe how bad this movie turn out to be and a the movie sound and look somewhat entertaining . this wasn not even so bad it be good . it be just so bad . a group of friend find themselves be kill off by a serial killer who knock at your door and and then kill you . well and at least that what i think . because barely any of the kill fit the title at all . the opening scene actually make me jump a little and and thats probably the only positive thing i have to say about this movie . open scene be good and but too short live . the acting be mostly so so to bad . the lead ( we will move onto her later ) be like a cheap attempt at a lead and and all of the friend she have be just annoy and undeveloped . none of these character have any character development whatsoever and you do not feel for them when they die . quickly . i can not remember any of their name and and some would disappear for long length of time and then die quickly ( after have about 5 minute screen time total previously ) . the detective be atrocious and be probably some of the bad cop you can ask for . the lead female detective dress like a call girl to work and and have a temper and a complete attitude on her . i do not know a cop could slap someone in an interrogation and and get away with it . they do the bad detective work you could ask for and and do not seem bother by the fact that and at crime scene and there would be limbs everywhere . oh yeah . what be the point of the wwe wrestler stephanie . cleavage . a if the movie do not have enough already . now and onto the lead girl . this be some of the bad characterization i have ever witness in film . the movie clock in at around 84 minute . the lead girl be first see in the first 5 minute of the film and for around 15 minute and disappears until the last 5 minute of the film . we do not see or hear anything from her character at all and it a if her character do not exist or the actress just walk out on set and they continue film . her boyfriend and who be make to look like the male lead and have the same thing happen to him . that be bad write right there . i couldn not believe this a i keep on wait for the lead and her boyfriend to show up . do not happen until the last few minute of this crap fest . the kill scene be just so rushed and you could only watch them with a straight face and just think lame . none of the character put up a fight at all and and would be kill very quickly and then they would be brutalize after be kill . i think this be the writer or director way of make it longer and when they just damn right suck . the whole plot just go from supernatural to slasher and it couldn not decide what it be . it be messy . the killer look like a reject from the texas chainsaw massacre and look like a guy dress up a leatherface for halloween . only and this guys face look like paper mache . i be go to end this review say that this movie have one of the bad extra i have ever see in a film . ever . during a flashback scene and one extra keep look towards the camera repeatedly and seem completely bore and uninvolved in the whole scene . he look completely lose and a if he do not know what he be mean to be do . but i be not surprise in a way . because this be a bad movie period . negative .
