Terminator 2: Judgment Day (1991)

In this sequel to the 1984 film, the same terminator that tried to kill Sarah Connor comes back again. But this time in the year 1994 and is assigned to protect her and her son from the T-1000, a more sophisticated terminating machine made of liquid metal. John is now ten years old and in a foster home while Sarah is locked up in Pescadero State Hospital, a mental institution. A juvenile delinquent that has been in trouble more than once, John is shocked when he meets the terminator but remembers his mother telling him about it. When his foster parents are killed, John orders the terminator to help him bust his mother out of Pescadero. Once they do that, they prepare to fight the T-1000, getting weapons ready and transportation. But Sarah has other plans in mind; she takes off on her own mission to kill the man responsible, a computer developer called Miles Dyson so it will prevent the war from happening. However, John wants to stop her so he and the terminator go to his house before she does. They then plan to destroy all of Miles's work at the lab, including the chip that was saved from the previous terminator. A roller-coaster ride; with even more awesome special effects, this is one of the best sci-fi sequels ever made.
