Why does Sadako kill the people that watch the tape?
Couldn't she just have not?
i know it wouldnt make much of a film if you had a ghost that wasnt bothered who watched her get brained, but yeah.
not a lot of motivation for her tbh.
also do you reckon if 2 people watched it at the same time then a week later were in seperate places she'd get them at the same time? surely if there was enough people in the room at the time they could do her in again, but properly this time.
oh and why did her dad film her being killed? and then allow it to be rented from a hotel.
