There seem to be four phases of the movie:
- The beginning where Sara is locked in the mental hospital, and John O Conner is acting out his frustrations. The two terminators arrive from the future, one to protect John, one to kill John.
- Terminator to Terminator warfare, lots of nifty special effects.
- The race South to get weapons. This is also where we have the major relationship building phase.
- The battle to destroy the original terminator parts stored at Cyberdyne and the last battle of the terminators.
I always find time travel movies interesting. I am not sure the idea of going back in time makes sense, time seems to move forward. It stopped once, in one way or another, or at least the sunset was held back, but never went back. Assuming you *could* go back in time, the thought that one person could change history is a bit overdone. There are lots of people playing on the stage if you get my drift.
