A few days ago, I saw Falling Down (1993) for the second time or so.
(Spoiler ahead, if you managed not to see this movie yet)
During the movie, which in real time covers the best part of a day, William Foster, clearly in a violent mood, threatens to visit his ex wife, Elisabeth, to attend their little daughter Adele’s birthday party. He calls her a number of times. She is terrified of him and notifies the police until they get fed up with her and don't offer her any protection any more.
Beth stays at home, knowing that William is on his way. Isn't that strange? When she finally runs, William is already entering her house.
I understand that the plot needs suspense. But my question is, is it made plausible in the movie itself why she lingers so long?
(I randomly sampled the haystack of 346 reviews at IMDB, but no luck).
