It was awesome. The effects and robots were beautiful, the action was incredible, the characters were good, and the plot, while not outstanding, was still solid, and for a movie like this, come on. It delivered. I only wish the other robots could have gotten some more action. But, it still is an incredible movie.
Don't know why some people complain so much on technicalities and science and physics when it's a movie about Giant Robots fighting Giant Monsters.
