This was a good movie. When it first came out I really had no desire to see it, I didn't care about the transformers. I had heard that it was a good movie and so we rented it. It is packed with action. It's a pretty long movie, 1 hr and 23 min, but it keeps moving the whole time. If you like action packed movies and special effects you will love it. The transformers come to Earth in search of the "cube". It is an energy source that creates life. Megatron, the head of the evil decepticons, wants to find it and take over Earth's technology and get rid of the humans. The good autobots are led by Optimus Prime. Each transformer is a car, truck, plane, etc. that transformers into a huge robot with special abilities. The movie begins at an air force base in the middle east that comes under attack by some huge machine. A few survivors are left who contact the gov't. and try to stop the transformer. The machine has somehow hacked into military computers and taken all the information it could. From here the movie turns to high school student Sam out to get his first car. The car, a transformer named Bumblebee, really chooses him. Eventually Sam meets all the transformers and learns of the cube and how they hope to save the world. Optimus Prime wants no humans hurt, only to stop Megatron from obtaining the cube. Sam has a tie to Megatron in that his great-grandfather discovered him while exploring the arctic circle many years before. Megatron was frozen in the ice and Sam's grandfather activated something on him that produced a laser and imprinted the map of the cube's location onto his glasses. Sam now owns these glasses and is trying to sell them on ebay. That is how the transformers find him. From here it's just action packed. There is a subplot with some computer experts trying to trace the source that has hacked into the military computers to steal all their information. A lot goes on in the movie, but it is not hard to follow. I would recommend this movie if you're looking for a good, fun action movie. It's funny at parts, has a good story and keeps you watching the whole time.
