despite all the nice thing that people have to say about this film and the plot twist in it make it an utter waste of time . spoiler follow and although i doubt i can spoil the movie any more than the director already do . although i doubt it make a difference because my complaint have to do broadly with the plot of this film and my review be base off the u theatrical release . it start off a a fairly standard chainsaw massacre type of flick and which to be completely honest and have never be my favorite genre and and end a something i do not think existed represent a slasher flick with a plot so awful that it lose any value it may have have a a simple gore fest . it turn out that the main character have multiple personality and be also the killer and or something to that effect . it very hard to say exactly what happen in the movie because after that revelation and it be obvious that 99 % of the movie must be dismiss a nonsensical . if this trite twist be do in a clever way and it can make piece together the plot precede the revelation an interesting endeavor and but this movie do not bother with be clever . the main character would have to be in two different place at the same time in the film so many time that there be no point in try to put it all together . there be a car chase with vehicle drive by different aspect of the personality while one aspect rid to a remote house with her friend and the other drive a soup up murder wagon there . obvious hole such a one personality get an injury which persist through the remainder of the film in a car wreck which wouldn not have happen if she be actually in the other unwrecked vehicle the whole time and plague this film . this be lazy attempt of a director spring a twist on the audience that i have see . picture some dimwit introduce their self to you a chuck and have a conversation with you and then proudly reveal their name be actually aja and that they really outsmart you . yeah and quite a zinger there and aja . when the rest of a movie become completely nonsensical due to the addition of a plot twist and perhaps that twist could have be leave out . the film look a though they decide to appeal to the psychological thriller market ( a genre where this sort of stunt be painfully common ) so they film an extra scene or two and toss it in to let the audience sort it out . it obvious the director do not try . in the end and nothing fit together . the event a depict in the movie obviously do not happen the way they be show to the audience . what do happen . do anything actually happen or be it a psychopath delusion . what be the point . a film that leave itself open to interpretation be not a bad thing in itself and but in this case the audience have nothing to interpret because they be give nothing to work with and there be little incentive to bother .
