Missed opportunity with the wig for a big scare!
Ok, maybe it wouldn't have scared ME since I already thought going into the scene that they were going to do it . . .
But wouldn't it have been creepy if the scene had played out like this.
Megumi is placing the wigs on the rests, one by one - starts to hear the noise from the closet. Goes over to investigate - the wig falls on the floor. Then she picks it up, the camera follows her down. She picks it up, and puts it on the rest, and in the mirror we see the rest is actually the ghost's head! Cue loud music for big scare!
Something like that - I also thought they could have had her brushing the hair, then after a few shots of seeing only the rests in the mirror, we would tilt down to the one Megumi is brushing and suddenly see that it is the ghost's head!
