I was quite blown away with the visuals. I hope they win an award for it. Sometimes, you can tell the studio is trying to cut costs so they skimp on the visuals but they didn't.
Some of the plot surprised me. I wasn't expecting the movie to take place 12 or so years after the attacks began. I was also surprised it focused more on the girl and the scientists than the main guy. All in all I think I have a new addition to my dvd library.
