Let's see... dozens of young women vanish after babysitting this girl. The parents have reported this occurrence three times to their current babysitting agency, yet no one is suspicious? No one is looking into the disappearance of dozens of young women? No one has called a cop? And no one, not even the parents see a connection to their last known babysitting job?
Also in addition to the above goof- the parents never notice that the girl's doll collection continues to grow without explanation. Where did they think these dolls were coming from anyway?
