spoiler i rent tesis ( or thesis in english ) on the strength of director alejandro amenabar later effort the others . base on what a brilliantly measure and horrifyingly effective creepfest that film be and i assume his early effort would be of a similar quality and i be in the mood for some good horror . instead i wind up with the most tedious and preposterous excuse for a lame brain slasher movie i have see since the german film anatomie ( which this one kinda remind me of ) . the plot have potential but it thrown away within the first 20 minute . it revolve around innocent n pretty psychology student angela ( ana torrent a jessica harper deadringer ) thesis on the subject of violence in film . through some far fetched circumstance too dumb to go into here and she wind up in possession of a nuff tape on which two men torture and mutilate and kill a young girl for the camera . angela and and her horror buff friend chema ( fele martinez ) be both shocked yet intrigue by the tape and decide to get to the bottom of who responsible for it . this lead to . well and nothing . they never really give a reason for why they want to find the girl killer ( since they resolutely refuse to contact the police throughout any of the unfolding event and even when their own life at risk ) and the mystery itself be as limp a graham norton in a room full of bunny girl . there be only one proper clue ( the type of camera the killer use be discover ) and that a ) a really weak one and b ) wheel out in the first 20 minute . the rest of the so called unravelling just occur through blind luck and increasingly ridiculous plot twist and a slew of awful and transparent and thoroughly pointless red herring that be chuck in merely to pad out the running time . seriously amenabar might know his stuff about ghost story but he clearly never read a detective book in his life . the key to a good whodunnit be to have a large cluster of potential suspect and to eliminate them one by one with clever deduction and the gradual discovery of more and more evidence and before move in for the final twist . in tesis and potential spoiler ahead the killer identity be guess correctly by the amateur wouldetectives almost instantly and then we get 100 minute of the writer try feebly to throw u off the scent until he run out of idea and throw his hand up and say ok and ya get me and it be him after all . a for any kind of logic or motive behind the crime no such luck . youre watch the wrong movie if that what youre after . the only thing that drag tesis down far from just be a dumb and badly write thriller be the way it actually try to make some ludicrous and muddle up point about violence in film . i have no idea what stance it attempt to take on the subject but it seem determine to cram in a ton of misguided and confused psychobabble and in between the rest of the gibberish and and say look at me . i be political . the final scene and in which the point of the movie be supposedly hammer home and be so utterly absurd and puerile and one can not help but wonder if amenabar feel embarrass now when he watch this . if he doesn not and he certainly should . this be total amateur night at the slasher house stuff . overall i can not believe i waste two whole hour ( it felt like at least six ) on this and just hop something might happen . the urban legend of nuff film ( and that be basically all they be and despite the way this film try to suggest theyre some kind of criminal phenomenon sweep the world . ) be an area that can be so tantalisingly exploit in good horror film ( videodrome anyone . ) but it so easy to step over the line into childlike wouldn not it be cool if . territory with it ( ie represent my little eye ) . tesis hit an all time low for the nuff movie genre . on every level and this one be well leave dead and buried . i will award it a negative and for some nice lighting and but that all it get .
