Corrected entry: Why did General Brewster say that he was sending John Connor / Katherine Brewster to the Skynet core (so they could bomb it), yet give them the access code book for the 1950s bunker?
Corrected entry: In the military bunker, the TX morphs into Catherine Brewster, yet the T-850 states in an earlier scene that the TX has to have touched whatever it turns into. The TX doesn't touch Brewster before morphing into her; and if she had she would have killed her.
Correction: She touches her when she throws her out of her van at the beginning, not to mention steps on her head interrogating her.
Corrected entry: When Arnold is carrying the casket out to the hearse, he takes on heavy fire, yet later on there is not one bullet hole in his leather jacket.
Correction: He has several bullet holes all over his jacket that can be seen throughout the entire film.
Corrected entry: When John and Catherine are in the bunker, John remarks that the computers are over 30 years old. However, there are a number of brand new Dell cardboard boxes with older equipment sitting on top of them. There are no new computers anywhere in the complex. (01:35:00)
Correction: Its entirely feasible to assume that upgrades were eventually going to be made to Crystal Peak's systems. The 'new' Dell boxes could have been hardware that was not yet installed. Also note that those 'new' Dell boxes are the same boxes that Dell has been using for years to ship its computers in. It is unclear how old those Dell boxes actually are.
Corrected entry: In the scene where Catherine is in the back of her van she calls 911 for help. They show her looking at the scene of the phone with no signal bars, yet she starts to talk to someone.
Correction: Most phones only show signal strength for the network that your phone is on, but if you dial 911, they will connect you to another network that has service in the area you are in.
Corrected entry: In the scene where the TX is being overpowered by the magnetic field, why isn't Catherine's large metal watch similarly affected?
Correction: The watch was probably made of a steel alloy or metal that is none magnetic. Most alloys of stainless steel are not affected by magnetism. Neither is titanium or aluminum, all common alloys and metals in watches.
Corrected entry: In the scene where both terminators are fighting each other in the bathroom in the underground military facility, there is water spraying from the damage but neither of them get wet.
Correction: Arnold is visibly wet as he walks through the water. He is also wearing leather. Water tends to run off of Leather quite quickly. As for the T-X, her skin is liquid metal. It is likely that water rolled right off her.
Corrected entry: At the gas station where Arnold picks up the chips and snacks, John and Catherine get in the back of the truck. The crowbar used to lock the back door is not put back into place. The next scene shows the truck driving down the road with the crowbar visible in the back door. Yet later when they reach their destination and the back door is opened, the crowbar has vanished.
Correction: At the gas station, Arnold pulls the crowbar off and throws it to the ground. That is the last we see of the crowbar. He doesn't put it back, nor does it appear on the truck as they drive away. At the cemetery he simply opens the door, with no crowbar.
Corrected entry: In the scene where the cops and fire fighters arrive at the Animal Hospital, no one bothers to question the only other civilian at the crime scene, the T-X.
Corrected entry: When they leave the vets office and crash into a car, the rear end of the car is totaled. When they drive off, the Tundra's front end is perfectly fine.
Correction: The Tundra actually has a bit of damage. Look at the car it smashed in to. A Ford Taurus. It weighs less than half as much as the truck. Of course the car would suffer more damage than the truck.
Corrected entry: The tool chest that Catherine is thrown into changes position from when she hit it to when she is getting ready to climb into the plane with John.
Correction: It doesn't change position other than when she hit into it, causing it to move. She crawls away from it while John and the Terminator are struggling.
Corrected entry: In the cemetary scene, The Terminator counted every single round fired from the chain gun. In a later scene in military compound where Catherine's father is located, The Terminator uses a rifle. When confronted with the T-X, he fires with an empty clip. He should've known he was already out.
Correction: Perhaps the weapon was not out of ammo, but had jammed.
Corrected entry: Skynet becomes pervasive by behaving like a computer virus. It infects other computers via the internet and takes control over them. Skynet uses this power to initiate an attack against mankind. However, since most power plants, network administration nodes, and personal computers reside in the cities, Skynet would be destroying both itself and the manner in which it operates when the cities are destroyed.
Correction: Skynet is a very intelligent machine/program, it would weigh the consequences and accept losses of a military action and probably move itself to a secure location. Skynet would know of places where it could obtain power to sustain itself. Skynet could also possibly store its key data in a robot like a Terminator that was able to move under its own power.
Corrected entry: Why did the T-X even bother to get herself a uniform when she could have easily killed someone and shape shift into them?
Correction: She never stole any clothes, just the car. She just patterned her look after the clothes of the first woman she saw. Notice how her outfit "heals" just like her body after she gets shot, just like the T-1000 from Terminator 2.
Corrected entry: How do John, Catherine, and the Terminator gain access to the military compound where Catherine's father is located? We can assume that the T-X gained access using her ability to disguise herself, but our heroes just waltz in to try and stop her. Surely there would have been tight security to prevent unauthorized personnel from easily gaining access to the facility, not to mention the command center.
Correction: There is a scene just before this in the building that shows guards and others lying dead at her feet. John, Catherine, and the Terminator could get in because those who would've stopped them were dead.
Corrected entry: When the Terminator crashes into the T-X with his pick-up, they crash into a building. Instead of blowing the building up, the building next to it (as well as the silver Audi) bursts into flames instead.
Correction: This happens because Arnold crashes the truck into the building, causing the car to crash forward into the other 'building'. However, that 'building' was a power station, hence the power station blew up when the car was thrown into it, causing the flames.
Corrected entry: Why did the T-X shoot the cat lady without first asking for Katherine Brewster? For the lieutenants she asked their names to properly identify them, then she shot them.
Correction: She needed to ask them first because they were around other people. If she just started shooting people at random the person might escape in the ensuing panic. Since the cat lady seemed to be the only one there, shooting her first then identifying her doesn't seem that unreasonable.
Corrected entry: When trying to escape, Kate is thrown several feet from her car by the T-X. Surprisingly after such force, her cell phone still manages to survive the impact (which she later uses to call for help).
Correction: A cell phone could survive the force easily especially if it is padded by Kate's clothes.
Corrected entry: How does Arnie hold up the blast door? He has one hand holding the TX from going through and another busy trying to take out his fuel cell. How does he keep the blast doors up if he only has two hands?
Correction: When he initially stopped it from coming down, you can see that th gears screech, spark and jam. He successfully managed to break the gears, so the blast doors were jammed in that position.
Corrected entry: Before we get to learn that Catherine is the T-850's master, he never obeys any of her commands and answers all of John's questions, but only after T-850 explains that Catherine is his master, he starts to behave like her lapdog and refuses to answer any of John's questions. Why the sudden change of behaviour?
Correction: She never gave him any commands he could obey. Like when she said "Drop dead", he said "I am unable to comply." And the T-850 could answer most of John's questions, just not any about the future. Once it was revealed that Kate could control him, she made better use of her commands.
Correction: Since General Brewster was aware that John and Katherine would not be able to destroy a (nonexistent) Skynet Central, he never actually sent them to Skynet Central but to the bunker where they would be safe from the nuclear war. John Conner afterwards explains that Skynet had no central core anymore but was located decentralised all over the world, using the web to spread (maybe even the military was responsible for this in order to minimize danger to Skynet). It was John and Catherine who assumed they were sent to Skynet Central, which, according to the novels, was not located at Crystal Peak but at Cheyenne Mountain and Navajo Mountain bunker bases.
