okay and i have reasonably high expectation for this . the controversial subject matter be a good concept . a a horror fan i admit i be fascinate and very excited about this . it turn out they have a great idea and but it be terribly execute . let see . this movie seem to run in 3 mode represent happy and sex and dark . the problem be that the movie never decide what it want to be . the happy part i believe be mean to contrast with the dark part and but it doesn not work . the soundtrack be one of the reason . the movie transition between these 3 mode very badly and i can not even begin to say how much the directing and edit suck . there sex in the most unappealing and unerotic way . i be not complain but even for horror standard they be unnecessary and filler . the character be all unlikeable with the exception of paula ( potente ) . her friend from munich be a slut and possibly one of the most annoying character in movie i have come across recently . there a bit of plot which i would not go into detail . it not stupid and in more talented hand would make a good movie . there even a nice twist and a cool conspiracy go on . don not try to understand everything because there be giant plot hole here . it all so shoddily do that you do not care for the victim and the perpetrator and anyone . and to think this could have be great . i can say one good thing about it which be and the movie shed some light on today unethical medical procedure . with genetics and controversial science advance and this could have be a great philosophical film that raise and discuss these question . but you would not find that here and just a series of scene loosely paste together with people and thing that you do not care about . skip this and go watch flatliners instead and youre welcome . negative .
