And it made no goddamn sense.
The story goes that the second skynet gained consciousness, it released about 50 nukes to wipe out humanity. However, as we know, nuclear weapons not only cause huge life form casualties, but also great material damage. So how the heck, after whole world got nuked to fuck, could it build an army of robots?
As far as I know, it gained consciousness by injecting itself into the interned web, taking over all computers in the world. Then it goes and destroys not only most technology on planet earth, but also source of power for all electronics, because power plants would be destroyed along with all other stuff. Not to mention there wouldnt be anyone and anything to run them.
Not only that, but humans would not have any actual chance of survival, even in those nuclear shelters. It was a fucking catastrophe when Chernobyl plant exploded, now imagine 50 explosions that are several times stronger. The world as we know it would literaly fall apart, with ozone shield gone, it would get burned to crisp. And even if we ignored that, there is still massive radiation pollution EVERYWHERE, and athmosphere would also warm up tremendously.
There is other stuff, but this has seemed to me as the worst story-wise crime in the series as whole.
