Too many plot flaws to be good.

Rating: 3/10 (19 December 2005)

The first Terminator had good special effects and a good plot. The second had really good effects and a decent plot. The third had great effects and a weak plot.
The explanation at the end is what really bugs me about this movie. They claim that they couldn't shut down the machine brain because it wasn't just in one place, but existed spread out in servers all across the country.
The thing is, that's stupid. If that were the case, then the artificial intelligence would have died shortly after it launched the nukes, because all those servers would have been destroyed. It would have been like taking a large knife, trying to remove your nose by jamming the blade straight into your skull. Sure, you'd get rid of the nose, but it wouldn't help your brain much.
Also, the idea that the Terminator had killed Conner in the future and was sent by his wife is flawed. Way back in the first film, we learn from Kyle that the human revolt against the machines had been successful, they had already won. Sending the Terminators back was a last-ditch effort to prevent that defeat. Therefore, there should have been no Terminator sent after John years after the machines were defeated.
Also, in the first movie Kyle says that the time displacement equipment was to be destroyed after he went thru. From T2, it's obvious that they sent the second one after he went. However, it's hardly likely that they would change their minds and not destroy the time machine after that; they already knew what a problem they were facing with just the two Terminators that had gone through already.
Also, if John's learning that he's going to get killed by a Terminator in the future (which he was told), then he should be able to avoid it.
Not to mention that a nuclear-safe bunker set up for VIPs wouldn't have obsolete computers, radios and other equipment; restocking and updating it would be a periodic activity.
There are so many basic plot flaws in this movie, the only value it has left is the special effects.
