Continuity mistake: When the man who was holding the carollers hostage comes to Davis', she dives behind the fridge door, the man shoots the door and Davis flies backwards. After he kicks the door shut, there's not a scratch on it.
Suggested correction: In every shot after the one-eyed man shoots the door, there is a huge black burn mark on it, both the handles for the refrigerator and freezer are missing, and the handle brackets are twisted and jagged. There IS a mistake here though. When Samantha opens the refrigerator door and when the man kicks it, the refrigerator and freezer doors have obviously been fastened together and move as a single door. In a previous scene we saw that they open independently.
