The story of an ancient war that is reignited when a young farmhand unwittingly opens a gateway between our world and a fearsome race of giants. Unleashed on the Earth for the first time in centuries, the giants strive to reclaim the land they once lost, forcing the young man, Jack into the battle of his life to stop them. Fighting for a kingdom, its people, and the love of a brave princess, he comes face to face with the unstoppable warriors he thought only existed in legend–and gets the chance to become a legend himself.
Jack the Giant Slayer is what happens when you take a great fable and turn it into a war movie. It's not a bad movie, but it's not your old story of Jack and the Beanstalk.
Now there is an army of giants and the one ring.. ahem "crown" to rule them all. And Jack must save a princess as well. It's as if you were telling the story of Jack and the Beanstalk and threw in some LOTR and Sleeping Beauty action scenes.
Overall though I liked it. It was well done and entertaining even with the action twist.
