you probably know the story by now represent two girl ( marie and alex ) go to marie parent country house to study . a deranged french redneck killer appear and start kill them for no reason and with alex escape and fight him . in the end and it turn out ( fight club style ) that alex be in fact the killer and and that there be no redneck to begin with . whoopieee . if alex be the killer and then 90 % of the movie involve alex fighting or run from the redneck do not happen . make for a truly satisfying aftertaste . and how come alex go out of the blue so completely freakin insane that she kill 4 people in gruesome way and yet have be friend with the unsuspecting marie at college for a long time ( and and apparently and display no symptom whatsoever ) . turn out she a dyke with a secret crush on marie and which drive her insane . . and make her cut her mother fist and kill her little brother with a rifle . . or something . anyways and the alter ego fight club ( and x other movie ) like twist in the end serve only to justify the completely unlikely plot and over the top bloodshed before and and inadvertently ( unlike in fight club ) and make 90 % of what we have see totally illogical and impossible to have happen . fight club work because the protagonist and his alter ego always occupy the same physical space . this do not . here we eg . see alex try to untie marie and a they both watch the killer outside kill marie young brother in the cornfield . etc and etc . dear director and the person and it persona can not occupy two different space and perform two different action at the same time . this only show that the twist be a poor gimmick that easy to fall for at first and but when you rewind the movie in your head in light of it and you find it just doesn not work and the whole movie just doesn not make sense . and if alex kill her killer alter ego in the end ( i. e. cure herself of evil ) and why do he appear again . cheap . plus and you have get muse newborn a a score ( appear twice ) . imagine combine the plot above with muse . self aware and stylish and cheaply manipulative . for those easily shock and reluctant to give a second thought about anything .
