Terminator Salvation
Another movie that is into his 4th instalment, a 5th one is in the pipe line. Machines continued their intention to take over the world and that means kill all humans. The resistance, a group of army personnel determined to stop the machines. They were led to believe that some signal if used will be able to stop the machines, their tests proved them right. But what John Connor by Christian Bale, didn't know was, it was just a ploy by the machines.
Then came along this Marcus guy by Sam Worthington, a machine but strongly believes he is human, till he saved Williams, a resistance pilot. She brought him back but he accidentally got injured by a mine. The injury revealed his inner machine build, thus got imprisoned. W believed M is good and release him, leading J out to destroy him. He didn't manage to but came to a deal. M promised to lead J to Kyle Reese, a young man now but is J's father.
M went back to the Machine HQ to seek some answers. And he got them, he is a human machine deployed to lure the resistance in, a machine with a pumping human heart. Something which previously no machine could do. M got J in and as he tried to find Kyle and save the rest out. He found a machine, none other than the cameo appearance of Arnold S. While the humans are out, J was still inside and met T 800, the newer, faster and even more hiong machine. He was no match for it, M came along but was knocked unconscious with his heart stopped. But J revived him and M manage to stop the T 800 by tearing off his head, though J was already pierced through by a metal rod.
They escaped with the HQ blown away and ended with M giving J his heart so to save J life. Straightforward machinery action, maybe one day all technology equipments will begin to kill all IT guys. 7/10
