Corrected entry: When Serafine turns into a werewolf, her knees bend backward and turn into hocks (the equivalent of the human ankle). And her upper leg bones bend forward to become stifles (the equivalent of the human knee. Since wolves and humans have very similar leg structure, there would be no need for her joints to do this. All that would really be needed is a lengthening of her bones from her ankles downward. Instead, she now has an extra set of joints in her leg.
Corrected entry: In the scene where Andy is in the morgue looking at the girl's body he is accompanied by the police. It would be very unlikely that they would not handcuff him let alone leave him in the morgue by himself so he can escape since he just murdered someone.
Corrected entry: Andy is in the bedroom after his attack. He falls out the window and suddenly his socks are on.
