 Daniel Farrands , writer of The Curse of Michael Myers , describes the character as a " sexual deviant " . According to him , the way Michael follows girls around and watches them contains a subtext of repressed sexuality . Farrands theorizes that , as a child , Michael became fixated on the murder of his sister Judith , and for his own twisted reasons felt the need to repeat that action over and over again , finding a sister @-@ like figure in Laurie who excited him sexually . He also believes that by making Laurie , Michael 's literal sister , the sequels took away from the simplicity and relatability of the original Halloween . Nevertheless , when writing Curse , Farrands was tasked with creating a mythology for Michael which defined his motives and why he could not be killed . He says , " He can 't just be a man anymore , he 's gone beyond that . He 's mythical . He 's supernatural . So , I took it from that standpoint that there 's something else driving him . A force that goes beyond that five senses that has infected this boy 's soul and now is driving him . " As the script developed and more people became involved , Farrands admits that the film went too far in explaining Michael Myers and that he himself was not completely satisfied with the finished product .
