Mistake 1 The scene where the elementary school teacher asks his kid what they did
that week. After he asks that question and Maizy raises her hand, look at the desk
belonging to the girl in the row next to Maizy. It has crayons and other supplies
on it. After the teacher calls Maizy's name, the shot goes back to her, showing the
girl in the next row's desk completely empty.

Mistake 3 Buck comes out of the laundry room twice when Marcy comes over and thinks

and shoots oil/smoke in a boy's face. In the next shot no one is behind the car.
Mistake 5 In the scene where the dad tells the mom that Buck will be able to stay
