Arnold Schwarzenegger returns again as a terminator that has been sent back in time to save an adult John Connor from a more advanced robot (this time masquerading as a woman) that was sent back to kill his lieutenants and, if possible, him. But while this plot worked in the second movie, it does not go over so well in the third. The central theme of the first two movies was thrown to the side, and instead of people being able to determine their own future, the audience was told that there was absolutely no changing the future.
