SET in a post-apocalyptic future, Christian Bale stars as John Connor, the man destined to lead the human resistance against Skynet and its army of deadly Terminators.

But the future Connor was raised to believe in is altered in part by the appearance of a mysterious man called Marcus Wright (Sam Worthington), a stranger whose last memory is as a prisoner on death row.

Connor must decide whether Marcus has been sent from the future, or rescued from the past.

As Skynet prepares its final onslaught, Connor and Marcus both embark on an odyssey that takes them into the heart of Skynet's operations, where they uncover the terrible secret behind the possible annihilation of mankind.

The film has been panned by many critics but despite not living up to the standards of the first two Michael Cameron offerings it is very watchable.

Featuring an array of cyborgs including motorcylcle Terminators and towering robots which seek out humans taking them prisioner and shipping them to Skynet the film is gripping throughout with lots of shocking edge-of-the-seat moments and fantastic visuals.

The best characters in Terminator Salvation are Sam Worthington's Marcus Wright who is very likeable and manages to attain his redemption with an heroic sacrifice and Anton Yelchin as a young Kyle Reese. Christian Bale lacks Sam Worthington's natural charisma and seems to take himself a bit too seriously putting in a menacing performance as a battle weary John Connor, using the same whispery voice as he did in Batman The Dark Knight.

Terminator Salvation works well as a movie on its own so you don't have to have seen all the previous Terminator offerings to enjoy it.
