An example of how bad this movie is

This is a BAD movie. It appears to have been made by rank amateurs. Horrible digital effects. No effort whatsoever at believability. Worst of all is the utter lack of regard for continuity.

Best example: the wife walks down a hallway. She pulls open a door -- wood-colored -- and walks through the doorway. In the next shot, you see her inside the room she just entered (a bathroom). The door is opened into the interior of the bathroom, even though she clearly opened the door toward her when she was in the hallway. Worse, the door was a natural wood color in the hallway, but is painted white when viewed from inside the bathroom. Of course film makers use different locations when filming a movie, but in a film made by anyone with even half a brain, at least SOME effort is put into the continuity.

This is, of course, a mere symptom of the bigger problem. Lack of budget is no excuse for bad writing and bad directing. It's just an awful, awful movie.
