Continuity mistake: While on a dirt road, the GPS tells them to turn around when they can. The car then starts to turn left. In the next cut, the car is turning right.
Continuity mistake: Gina's father opens the door, club in his hand, and finds his family inside for the surprise party. In the reverse shot, Gina's position is also mirrored, having the right arm raised instead of her left. (00:08:15)
Continuity mistake: When Chris drives up to Edgar's house, his windshield is dirty but suddenly clean thereafter. (00:11:37 - 00:12:57)
Continuity mistake: When Wyatt is shot, the amount of blood on his shirt next to the collar increases, decreases and even disappears between shots.
Continuity mistake: When we first see Agent Holloway viewing the crime scene photos taped to the wall, he is facing camera looking at transparent pictures on a transparent wall (as if we are behind that wall, seeing through it). When the angle changes to see the Agent from behind, the photos are now paper photos on a normal, opaque wall and the pictures are arranged somewhat differently - most notably to Holloway's right near the top where two wider photos are vertically aligned atop and below each other in the second shot when they were misaligned in the first shot by nearly half their width. The transparency versus opaque materials issue is a stylistic choice of the director and not a mistake, but the mismatched alignments is a mistake. (00:11:25)
