Excellent 3D visual effect from the beginning till the end. This is my first time watching movie 3D in theater. The people behind this movie were brilliant. I will give 5 stars for it. As for the story line, it suprised me. I thought for sci-fi would be a lot of fighting and laser shootings. But it tourn out it was pretty good. Sad,love,little bit humor, bad guy, good guy, it's all there. I'll give 4 stars for it. But still recommend it to see, just for the visual effect itself and the setting. IT"S WORTH IT after all.
