Terminator 2: Judgment Day 3D review – Arnie's sci-fi scorcher is still stylish, but is it essential?

The situation is one narrative step forward

from where we left the first movie. John Connor (Edward Furlong) is a kid but he is destined to be the grownup leader of the resistance to the machines’ post-nuclear tyranny. (As with all time-travel movies, you have to disregard the breakdown in logic: if we know he grows up, then how can any plan to kill him work?)
Linda Hamilton plays his mother Sarah Connor (a name that no one can see in print without hearing it in Arnie’s thick Austrian-American accent), who is confined to a psychiatric hospital because no one believes what she has to say about humanity’s future. Two cyborgs are sent from the future. The bad T-1000 cyborg, with the quicksilver power to change shape, intends to kill John and is played with a directional ferocity by Robert Patrick. And now Arnold plays a good cyborg, sent by the resistance to protect John.
