Continuity mistake: When "Ma" is driving down the road and sees her former friend jogging towards her, she swerves to hit her. In the close-up, the lady comes to a complete stop and throws her hands up. In the next shot from far away, she's running full speed at the truck again before she gets hit.
Continuity mistake: The IV bag has the name of Louie at first but then changes into something unidentifiable and then back to Louie again.
