When Laura fell from the white van, the back door was supposed to be opened. Yet when the white van crashed, the back door was closed. When they all climbed out of the van, the back door was opened again.
The heavy yellow air tank that Bronson was carrying changes in size. Also, the Sheriff has one air tank when getting into the truck, and Bronson ran to grab another air tank from the ground. Yet, later only Bronson was carrying an air tank.
The air tank changes weight - from almost too heavy to carry, to light enough to carry one handed.
Early in, the TR-4 runs somebody through the chest with his hand which is then bloodied. In the 5th minute, with clean hands, he twists someone's neck killing them immediately.
In the 20th minute as the sheriff and five survivors are escaping, none of the women are carrying guns but in the next scene they are all armed.
In the 58th minute when a T-4 punches someone through the back of his head impaling him with his fist, the victim would fall face down, not sideways and landing face-up.
In the 51st minute Bronson grunts as he carries the 'heavy' canister over his shoulder with two hands. But only a quarter of the canister is on or in front of his shoulder, his other three quarters behind his back. This is a telltale sign that it is not heavy, and likely even empty. He continues to carry it in this way in the tunnel. Though it is obviously light, each time he lowers the canister it makes a long thud.
During the truck bed fight in the 50th minute, each time Bronson is struck his cries echo, yet they are outside.
In the 78th minute the TR-4 rips the skin off the bottom of Bronson's face and the latter dies. This would not be a lethal injury, certainly not an immediate one.
In the 15th minute the sheriff has no shoulder epaulettes, insignia or name tag, only a badge.
In the 48th minute there are two people in the bed of the truck. As the truck is pictured from the side running into the TR-4, the bed is clearly empty.
In the 60th minute the sheriff is carrying the 'heavy' canister over his shoulder with one hand, and easily swivels it without effort.
Early in the film one of the terminators takes a pipe, places one end on the street and braces the rest with his body. A van races toward him, hits the pipe, and because of the angle vaults over the terminator, crashing onto a freshly plowed field. But when the camera goes back to the terminator, the pipe is not bent. Nor is it even dented. Just as if the pipe were never hit by the van and the whole scene was computer generated. The marvels of Hollywood.
In the 12th minute the TR-4 s breech the building without any security present.
It is unexplained why, in the 38th minute, the woman in the yellow top has blue/black on her top and body when she was previously covered in blood.
In the 82nd minute the new android impales one of the rescue team through the chest, but his arm does not protrude through the victim's back, unlike all such strikes from all the TR-4s.
In the 79th minute Kurt says "They've gone offline," but the TR-4 is clearly wavering rather than being still.
The TX-4s sometimes kill with guns, but more often with their hands. If they are bullet-resistant,it's unclear why they bother using a gun.
Roughly 50 minutes in the group is looking for fuel and the camera pans a metal building, continuing out to view the countryside and a couple roads. Society is being destroyed but there are a couple vehicles just driving along on the highway. No danger, no rush.
When they arrive at the empty warehouse, the footsteps continue while nobody is walking - shortly after the sound stops, people are walking but no footsteps are heard. This is on the long shot while they are walking outside.
In the 30th minute it is unclear why the woman falls out of the back of the van, as the door was not opened.
It seems surprising that the survivors, in an alien ship being pursued by other alien ships, could hit and destroy three of the latter, with no experience using their weaponry. Nor would they know how to navigate an alien ship.
The sheriff is a terminator and when shot, the "gunshot wound" hurts him. But if he's a terminator, it should not.
Kurt says that the only way to shut off the TRs is by the computer, however, Tiffany simply flips the switch to shut them off.
The sheriff acts exactly like a human being, right up until he finds out he's a robot. At this time, he's the stereotypical, monotonous android.
Early in the film a terminator repeatedly hits its victim numerous times. Eventually the head explodes as there is a sudden burst of bloody mass. But the Terminator keeps punching at its now quite obviously dead victim. If these machines are efficient, then they should only require one or two blows to kill their victim as they so often do in this film. Further, once this one's victim is dead, there is no reason for it to continue to bludgeon it. It should have delivered one or two blows, and most certainly ceased when it's victim's head exploded. But bludgeoning is something a human would do, an act driven by emotion. Whereas terminators are machines and therefore emotionless. So this bludgeoning is contrary to the very nature of a terminator and should not have taken place.
