My husband had to drag me to this movie because I am not a fan of fantasy or sci fi. But I have to say, I enjoyed every minute. My usual complaint is that these kinds of movies are all special effects and no story line, but this one is different. There is corporate greed, military might, and moral responsibility - it kept me engaged. The IMAX experience in 3D was fabulous! I never go to movies twice, but I would stand in line to see this one again!!
