This fourth film in the Terminator series may not please all fans,
since it is told from the exact opposite viewpoint of the first three, but
it is still decent Sci-Fi that furthers the storyline.
The first three movies told of Terminators being sent to the present from
the future by John Connor to save the life of his mother, and later his
own life. In 2018, John was leading a resistance battling a machine called
Skynet that had taken over the world and planned to extinguish all humans.
It had sent back terminators to make sure he would never exist. While
there were a few short glimpses into a dreadful future, basically, all
three movies were based in the present.
In Terminator Salvation, the time is 2018, and we follow John as he fights
Skynet, and also fights to ensure his own future, because Skynet is
looking for the man that John sent back first, Kyle Reese, who as it
turned out was John's father, in order to eliminate him, thereby
eliminating John.
There is no single Terminator to battle in this one, rather a whole raft
of them, in various shapes and sizes, but the movie does fill in some plot
holes from the previous three, and while it is my least favorite of the
bunch, it still wasn't bad. The caps are from the Blu-ray version.
