Plot hole: When Ana is driving away from her home, she stops on the road and a guy opens her door, scaring her into turning her car toward the curb, plowing through a guardrail. She couldn't have picked up a lot of speed, and those guardrails are supposed to always be reinforced on highways/interstates. At that angle she would have had to knock out at least 4 reinforcing beams (they use 'I' beams to reinforce them, and are intended to stop vehicles from passing through them, or slow them down immensely).

Factual error: When they are eating, there's a box of chicken labelled PFK (Poulet Frit a la Kentucky), the French equivalent of KFC. This film takes place in the USA, but was filmed in Canada where most products are labelled in English and French.
Trivia: The sheriff in the movie was Tom Savini, who did the makeup and special effects in the 1978 version and also had a cameo as a biker in the '78 version. (00:25:35)
Answer: It was actually explained in both versions that the zombies went to the mall because it was a place of familiarity, a place that they could remember even if they didn't know why.
