At 1:04, Sarah and Danielle have escaped from the dogs and are in the house. Sarah tells Danielle that she is going to get her father's gun. Next scene, Sarah runs outside to rescue Danielle and has no gun and does not get the gun when they get back into the house.
As Rosalyn is calling Sarah, you can see the iPhone's slide to unlock message flashing. Which would indicate she is not actually calling.
When the dogs are attacking the townspeople, the same man is shown dying on three different occasions.
Rosalyn calls for help to different people. She calls Sarah once. But when we see Sarahs phone, she has 2 missed calls.
At 0:16:09 to 0:16:19 a meteor is seen in the hillside above Mel's Automotive Repair. The meteor disappears from the hillside for the rest of the garage scene despite the camera angle being the same.
Meteors don't leave trails until they move through atmosphere.
Meteors don't make noise unless they're close enough to be dangerous. When seen at a distance, they don't go "whoosh".
About a half-hour in, it shows people picking apples up off the ground and from trees, with ladders leaning against what are clearly NOT apples trees.
When Rosalyn makes it to the orchard to get her dad, she is pulled out of the truck by a worker, and he starts to drive off. There is a tree directly behind the truck that shows the truck has not moved.
One of the townspeople shoots a dog in the side, and dog just stands there making no reaction upon the bullet's impact.
When the family is escaping via airplane, a dog is hit by the propeller and blood is splattered all over the windshield, but when it is lifting off, the window is clear.
When Rosalyn, Pia and Shep are in the abandoned truck, Rosalyn is hitting one of the wild dogs with a bat. It is clearly a rubber bat.
When Sara and Danielle are in the upstairs room, Max the dog is trying to get in through the door. The door knob switches sides numerous times.
Towards the beginning, when Rosalyn is driving the truck for a couple of minutes, you see the same view out of the back window the whole time.
At 0:27:36 when the dogs start to attack in town the seeing eye dog drags his companion into the street and is struck by a car. The shot switches to overhead and you see one of the camera operators standing behind a tripod leg in the top left corner. You can also see the very non aggressive dog from the attack wagging his tail and walking to that same corner with the recent service dog doing the same.
