this be one of my ultimate favourite film . it be not about the action but the fact that the main character be a sociopath . the film put so much detail into how he be to commit the act just to see if he feel anything and show how unemotional he really be ( this be the scary part ) . he choose the bad crime he can think of ( be a claustrophobic ) and then plan it meticulously . the end be shock when you put all the piece together of what he have do earlier in the film lead up to this and even involve his child scream to see how far it travel . i think the remake ruin the whole premise and meaning of the film and advise anyone to watch this one . he show no remorse just a morbid curiosity of other people emotion . truly a cold calculating scary man .
